Renting Out Your Ottawa Home While Posted Abroad: What Runs Itself and What Doesn’t

A posting runs on orders and dates. Your Ottawa house does not. The day a tenant moves in, the house becomes a regulated Ontario rental, Ottawa starts counting its occupied and empty days for the Vacant Unit Tax, and the CRA sorts your tax residency by rules that surprise most posted members. None of it pauses because you are overseas, and none of it requires you to be in Ottawa. It requires somebody to be.

The good news is that a posting is the most predictable absence there is. You usually know your departure date months ahead and your return window a year or more out. That lead time is worth money if you use it: the lease, the insurance change, the tax valuation and the City declaration all have dates attached, and every one of them is cheaper to set up before you fly than to repair from a posting.

Renting out your home while posted abroad works when the paperwork moves before you do. Every deadline in this article is knowable today.

Does a posting make you a non-resident for tax?

For most Canadian Armed Forces members and federal public servants, no. Section 250(1) of the Income Tax Act deems you resident in Canada throughout the year if you were a member of the Canadian Forces at any time in the year, or an ambassador, minister, high commissioner, officer or servant of Canada who was resident in Canada immediately before the appointment or who received representation allowances. The CRA’s page on government employees outside Canada applies the same treatment to federal and provincial employees posted abroad, and to people working overseas under a Global Affairs Canada assistance program who were resident in Canada within the three months before starting their duties.

Deemed resident means your rental income is taxed the ordinary resident way. You report it on your Canadian return each year, on the rental statement, and no withholding regime applies to the rent. Your posting changes your address. It does not change your tax home.

Everyone else has to work it out on facts. If your posting is with a private employer, an NGO or an international organization, residency turns on your residential ties: a dwelling available to you in Canada, a spouse or partner here, dependants here. Keeping the Ottawa house and renting it to strangers usually weakens the dwelling tie, because the house is no longer available for you to live in. It does not settle the question by itself. The CRA will give you its view if you file Form NR73 before you go, and that answer is worth having in writing.

If your status does come out as non-resident, a different machine takes over the rent: withholding, an agent remitting on your behalf, and a choice between filing routes with real deadlines. That machine is the whole subject of our non-resident landlord tax guide, and it is also the work behind RentSetGo’s property management for non-resident landlords. Read the guide before your first rent cheque, not after your first tax season.

What changes the day a tenant moves in?

Your home stops being treated as your home by almost everyone except you. The Residential Tenancies Act, 2006 governs the tenancy from the first day, and Ontario residency has nothing to do with it: the Act follows the unit, not the owner’s passport or posting.

The lease itself is prescribed. Landlords of most private residential rental units must use Ontario’s Residential Tenancy Agreement (Standard Form of Lease), and agreements signed on or after March 1, 2021 must use the current version. Clauses that conflict with the Act do not become enforceable because a tenant signed them. No-pet clauses and damage deposits copied from another province’s lease are the usual casualties.

The money at signing is capped too. The only deposit the Act allows is a rent deposit of no more than one month of rent, held against the last rent period, with interest owed to the tenant each year you hold it. Our first-time landlord guide walks the full signing sequence in order, and it applies to a posted owner exactly as it applies to a landlord across town.

Two clocks start running that owners abroad underestimate. Maintenance and entry rules run on local time: a no-heat call in January is an emergency in Ottawa whatever time zone you are sleeping in, and entering the unit takes the notice the Act requires, given by someone who is actually here. And the tenancy outlasts the lease paper. When a fixed term ends, the tenancy continues month to month on the same terms. Your tenant does not have to leave because the lease, or your posting paperwork, reaches its end date. The return plan in a later section deals with that.

If the home is a condo unit, add one more notice. Section 83 of the Condominium Act, 1998 requires the owner to notify the corporation in writing within 10 days of entering into or renewing a lease, and again when the lease ends. Condo boards enforce this, and a manager who leases condo units handles it as routine.

Who can act for you in Ottawa while you’re away, and where their authority stops?

A property manager works for you under a management agreement, and that agreement is the authority for the operational job: advertising the home, showing it, screening applicants under the Ontario Human Rights Code, signing the lease with the tenant on your behalf, collecting rent, paying the trades, serving the Act’s notices and keeping the records. You do not need to grant a power of attorney to get any of that done, and you should not grant one to a management company as a condition of service.

The authority has edges, and a posted owner should know where they are before departure.

• Board hearings. The Landlord and Tenant Board’s Practice Direction on Representation is blunt: a representative at a hearing must be a lawyer or paralegal licensed by the Law Society of Ontario, or a person in a category the Law Society has exempted from licensing. A manager who is not a licensed paralegal cannot argue your case at a contested hearing. Section 185(1) of the Act lets a licensed representative sign an application for you with your written authorization, which is how owners abroad usually handle it: the manager builds the file, a paralegal carries the hearing.
• Money and title. Selling the house or refinancing it is not management work, and neither is signing anything that gets registered on title. That takes you, your lawyer, or an attorney under a power of attorney you granted deliberately, usually to a spouse or family member.
• What a power of attorney can and cannot do. Under section 7(2) of Ontario’s Substitute Decisions Act, 1992, a continuing power of attorney for property can authorize the attorney to do anything in respect of your property that you could do if capable, except make a will. A power of attorney also ends at your death, so it is a posting tool, not an estate plan. If your family’s arrangements need one, have an Ontario lawyer draft it while you are still here to sign in front of witnesses.

Will Ottawa’s Vacant Unit Tax hit a posted owner’s home?

Only if the home is actually vacant, but the City does not take your word for it, and it does not excuse a missed declaration because you were overseas. Ottawa’s Vacant Unit Tax (By-law 2022-135) requires the owner of every residential property with six units or fewer to declare the property’s occupancy status for the previous year. Declarations open in January and are due by the interim tax due date, the third Thursday in March (March 19, 2026 for the 2025 occupancy year). Late declarations are accepted until April 30 with a $250 fee. An owner who never declares has the property deemed vacant, and the tax follows.

The vacancy test is a day count. A unit is vacant if it was unoccupied for more than 184 days in the year and is not a principal residence. The City’s tenanted category is the mirror image: tenants in place for at least 181 days of the year, in stretches of at least 30 consecutive days. A rented home with a stable tenant clears the test with room to spare. A home that sits empty through a slow lease-up, or between two tenancies across a year-end, can fail it.

Situation in the calendar year	What you declare	Vacant Unit Tax
Tenant in place at least 181 days, in stays of 30 days or more	Tenanted	None
You lived in it as your principal residence for the year, posting starts next year	Principal residence	None
Empty more than 184 days, not a principal residence, no exemption	Vacant (or deemed vacant if you never declare)	1% of assessed value in the first vacant year, rising one point per consecutive vacant year to a 5% maximum
Empty for a reason on the exemption list	Vacant, with the exemption claimed	None for that year

The exemption list is short and a posting is not on it. The by-law exempts a unit left empty because of the owner’s death, major renovations or redevelopment carried out under permit and without undue delay, the occupiers being in hospital or long-term or supportive care, a court order or proceeding that prevents occupancy, or a transfer of the whole legal interest to an arm’s length buyer. Being ordered overseas by your employer is none of those. If the home will sit empty, the tax is a budget line, priced off the assessed value, and it grows each consecutive year it stays empty.

Practically: the declaration is filed online and needs the roll number and access code from your property tax bill, or a MyServiceOttawa account. Leave a copy of the tax bill with whoever is watching the property, and put the third Thursday of March on a calendar that someone in Ottawa owns. This is where the tax actually lands in practice: in the City’s audit of incorrect 2023 notices, about 90% had a single cause, an owner who never declared.

What does your insurer need to know before the tenant moves in?

Everything, in writing, before the tenancy starts. A policy written on an owner-occupied home is priced and worded for an owner-occupied home. The statutory conditions that Ontario’s Insurance Act builds into property policies say it plainly: any change material to the risk, within the control and knowledge of the insured, avoids the contract as to the part affected unless the change is promptly notified in writing to the insurer or its agent. Moving out and installing a tenant is exactly that kind of change. The fix is a rented-dwelling policy or an endorsement agreed before move-in day, arranged through your broker, with the premium difference treated as a cost of the posting plan.

The gap periods need their own conversation. The Insurance Bureau of Canada draws a line between a home that is unoccupied (you live there, you are temporarily away) and one that is vacant (the occupants have moved out and nobody new has moved in). Policy wordings put their own number of days on vacancy, commonly around 30 consecutive days, after which some coverages shrink or stop unless the insurer has agreed otherwise. Your exposed windows are the weeks between your move-out and the tenant’s move-in, and any gap between tenancies mid-posting. Ask the broker what the policy requires during those windows, in writing. Heat kept on, water shut off at the main, and documented regular checks are typical conditions, and a home checking service during a gap is how owners satisfy them without conscripting a neighbour.

What happens to your principal residence exemption?

Something quiet and expensive if nobody plans for it. The CRA’s Income Tax Folio S1-F3-C2 (Principal Residence) sets out the rule: when you completely convert your principal residence to an income-producing use, paragraph 45(1)(a) of the Income Tax Act deems you to have sold it at fair market value and bought it back at the same amount. The gain to that day is usually sheltered by the principal residence exemption. The growth after that day is not, unless you elect.

Subsection 45(2) is the election built for exactly your situation. Filing a signed election letter with your return for the year of the change lets you be treated as if the change of use never happened: no deemed disposition that year, and the property can still be designated as your principal residence for up to four additional years while it is rented. CRA guidance notes the four-year limit can stretch further in some employer-required moves, under section 54.1, which is a conversation worth having before you assume a posting fits it. One trap is documented in the same folio: if capital cost allowance is claimed on the property, the election is treated as rescinded. Owners who would never claim CCA on a family home claim it on a rental without thinking. Do not, until your accountant has run both versions.

Two actions belong on the pre-departure list. Get a written valuation of the home dated close to the change of use, because the fair market value on that day is the number every later calculation leans on, and reconstructing it in five years is guesswork. Then tell your accountant the plan before the first rental return, not at filing time, because the election lives and dies with the return for the year the use changed.

How do tax bills and Board mail reach you abroad?

Slowly, unless you set it up. Canada Post sells a Mail Forwarding service for temporary relocation, which fits a posting better than the permanent-move version: a single service runs up to 12 months, with a three-month minimum, and it can be extended before it expires. Buy it in blocks that cover the whole posting so a property tax bill or a Board notice never lands in a tenant’s mailbox addressed to you.

Put the rest online. CRA mail, including notices of assessment, is viewable in CRA My Account, and the City of Ottawa’s tax and Vacant Unit Tax correspondence runs through MyServiceOttawa and the declaration portal. Your manager should hold a complete property file in Ottawa regardless: the lease, the tax bills, the insurance policy, the MPAC assessment notices and the utility account numbers. Originals of Board documents get served at the property or by the methods the Act allows, and the person holding the file is the person who can act on them the same week.

Before you fly, hand over or set up:

• The signed management agreement, with your contact chain and spending limits for emergency repairs.
• Written confirmation from your insurer that the tenanted use is covered, bound before the tenant’s move-in date.
• A dated valuation of the home from the month of the change in use, for the accountant and the subsection 45(2) election.
• A copy of the current property tax bill, because the Vacant Unit Tax declaration needs its roll number and access code.
• Canada Post temporary mail forwarding covering the posting, plus CRA My Account set up for online mail.
• A note of which utilities stay in your name during gaps between tenants, and who pays them then.

How do you get your home back when the posting ends?

By asking the Board’s process to run on your timeline, which means starting it early. A tenant does not have to move out because your posting ended or the lease term expired. To move back in yourself, the route is landlord’s own use: a Form N12 notice, with a termination date on the last day of a rental period or the last day of the fixed term, and at least 60 days of notice. Compensation of one month’s rent is owed to the tenant by the termination date, unless you give at least 120 days of notice, in which case the compensation requirement falls away under the rules in force since September 21, 2026. The person named on the notice has to actually move in and live there for at least a year.

A posted owner is oddly well suited to the 120-day route. Postings are usually confirmed months ahead, so the longer notice costs you nothing but a calendar entry, and it removes the compensation payment and most disputes about the date. If the tenant chooses to stay and wait for a hearing, only a Board order ends the tenancy, and hearing dates are the Board’s to set. Work backwards from your return flight: notice served four to six months before you land is planning, not pessimism. Our guide to Ontario landlord rights and responsibilities covers the own-use rules alongside the rest of the Act’s end-of-tenancy framework.

Segment the decision by what the posting actually looks like. Owners on a one-year posting with a cooperative tenant often renew and take the house back at a natural vacancy, because forcing the timeline costs more than it saves. Owners on a three- or four-year posting should treat the N12 dates as part of the posting itself, diarized at departure, not discovered at return. And owners who may sell instead of returning should know the choice changes the paperwork: a buyer who wants to move in runs their own version of the own-use process, after closing, with their own notice.

Can you manage it yourself from the posting?

Sometimes, and it is fair to say when. A short posting, a house in good mechanical shape, a tenant you screened carefully, and a competent adult in Ottawa who will hold a key and answer a furnace call will carry most tenancies. If your time zone is within a few hours of Ottawa and your employer gives you administrative time at tax season, the desk work is an evening a month.

It breaks at predictable points. Showings and lease-up between tenancies need a body in Ottawa for weeks at a time. LTB filings have service rules and deadlines that do not bend because you are mid-exercise or at sea, and a contested hearing needs a licensed representative or your own appearance by video at an Ottawa hour. The Vacant Unit Tax declaration, the deposit interest anniversary and the insurance conditions during gaps are all small tasks with hard dates, and they fail silently. RentSetGo’s full service property management exists for the owners who would rather those dates sit on our calendar than theirs. Which side of that line you are on depends on the posting, not on how capable you are.

What this guide can’t tell you

It cannot decide your tax residency. Deemed residence covers Forces members and federal servants by statute, but anyone outside those categories is a facts-and-ties question, and the answer drives which filing regime your rent lands in. Get the NR73 determination or an accountant’s opinion before you leave, while your ties are easy to describe.

It cannot price your employer’s help. Posting allowances, relocation benefits and any employer-paid management or vacancy coverage sit in your posting terms, and they differ between the Canadian Armed Forces, Global Affairs and civilian employers. Ask your relocation coordinator what is claimable before you assume a cost is yours.

It also cannot read your insurance policy for you. Vacancy definitions and day counts are set by your insurer’s wording, and two policies from the same company can differ. The broker conversation in this article is a prompt, not a substitute for the wording. Finally, Ottawa’s Vacant Unit Tax by-law has already been amended once, when Council raised the top rate to 5% in November 2024. Check the City’s declaration page each January for the current rate and deadline rather than relying on this article’s numbers in a later year.

The Bottom Line

Renting out your Ottawa home while posted abroad is a paperwork exercise with a house attached. Confirm your tax residency status before you leave, because the Forces and Global Affairs answer is deemed residence and everyone else’s is a ties test. Lease on the Ontario standard form, notify your insurer in writing before the tenant moves in, and get the home valued the month its use changes so the subsection 45(2) election stays available. File Ottawa’s Vacant Unit Tax declaration every year by the third Thursday of March, tenanted or not, because an undeclared home is taxed as a vacant one. Then diarize your return the day you leave: a Form N12 with 120 days of notice, served from wherever you are, is how the house is yours again when you land.

Frequently Asked Questions

I’m in the Canadian Armed Forces. Am I a non-resident for tax while I’m posted overseas?

No. Section 250(1)(b) of the Income Tax Act deems a member of the Canadian Forces to be resident in Canada throughout the year. Your Ottawa rent is reported on your Canadian return like any resident landlord’s, and the non-resident withholding regime does not apply to it.

Do I still have to file Ottawa’s Vacant Unit Tax declaration if my home is rented out?

Yes. Every owner of a residential property with six units or fewer must declare its occupancy status each year, due the third Thursday of March, with late declarations accepted until April 30 for a $250 fee. A rented home is declared as tenanted, occupied by tenants for at least 181 days of the year in stays of 30 days or more, and no tax applies. If you do not declare at all, the City deems the property vacant and taxes it.

What happens if my home sits empty between tenants during the posting?

Two systems start counting. For the Vacant Unit Tax, empty days add up toward the more-than-184-days vacancy test for that calendar year, so a long gap between tenancies can make the home taxable even though it was rented for part of the year. For your insurer, many policies restrict coverage once a home has been vacant for a set number of days, commonly around 30. Short gaps, documented checks and a tenant found quickly are worth real money here.

Can my property manager represent me at the Landlord and Tenant Board?

Only in a limited way. The Board’s Practice Direction on Representation allows a licensed lawyer or paralegal, or a person in a category the Law Society of Ontario has exempted from licensing, to act as a representative at a hearing. A property manager who is not a licensed paralegal can run the file, serve notices and organize evidence, but a contested hearing usually goes to a licensed paralegal, who can also sign the application for you with your written authorization under section 185(1) of the Act.

Do I need to give my property manager a power of attorney?

No. A management agreement gives the manager authority for the rental operation: leasing, rent collection, maintenance and notices. A power of attorney is a separate instrument, usually granted to a spouse or family member for banking or title matters. Under section 7(2) of the Substitute Decisions Act, 1992, an attorney under a continuing power of attorney for property can do anything you could do with your property except make a will, so it is not a document to hand over casually.

What happens to my principal residence exemption when I rent out my home?

Converting your home to a rental is a change in use. The CRA treats it as a deemed sale at fair market value on that day, and the growth after that day is exposed to capital gains tax unless you elect under subsection 45(2) of the Income Tax Act, which deems the change not to have happened and can keep the principal residence designation alive for up to four more years. The election goes with your return for the year of the change, and claiming capital cost allowance rescinds it. This is a decision for your accountant, made in the year you leave.

Can I move back into my home as soon as my posting ends?

Not on your posting orders alone. The tenancy continues until it is properly ended, and moving back in runs through landlord’s own use: a Form N12 with at least 60 days of notice ending on the last day of a rental period or term, one month’s rent in compensation unless you give at least 120 days of notice, and a Board order if the tenant waits for a hearing. Owners who know their return date should serve the longer notice and skip both the compensation and the argument.
