Estate Planning With Multiple Properties in Canada

A retired surgeon in London, Ontario, owns three properties when he dies: a fully paid family home in London, a cottage on Lake Joseph in Muskoka, and a Florida condo where he and his late wife spent winters. The London home is covered by the principal residence exemption for most of the years he owned it; the cottage was designated principal residence for the few years his children were teenagers and they spent more nights up north than in the city; the Florida condo is exposed to both Canadian capital gains tax (under the deemed-disposition rule) and potentially US estate tax. His will leaves the London home to his daughter, the cottage to his two sons jointly, and the Florida condo to be sold and the proceeds split equally. The probate work happens in Ontario (for the will), in Ontario again (for the cottage), and in Florida (for the US-situs real estate). Three probates, three tax exposures, three timelines.

Multi-property estates in Canada are common and have a planning shape that single-property estates do not. The principal residence exemption is a finite tool that has to be allocated across properties. Probate is a provincial process, so property in a second province typically triggers a second filing. US-situs real estate brings the US estate tax regime into a Canadian estate that otherwise would never have touched it. Each decision interacts with the others.

This guide walks the principal residence exemption allocation, the multi-province probate question, the US-situs estate tax exposure, the cottage-succession problem, and the executor-side mechanics of a multi-property estate.

The principal residence exemption is a finite resource #

The Income Tax Act allows a Canadian family unit to designate one property per year as a principal residence, with the gain on the designated property exempt from capital gains tax for each year of designation.^[1] Since 1982, the family unit (spouses and minor children) has been treated as a single unit — only one property can be designated for any given year.

For a single-property household, the exemption is automatic and uneventful. For a multi-property household, it becomes an allocation decision:

• Compute the per-year gain on each property over the period of ownership.
• Designate the higher-gain years for the higher-value property to maximise the total exemption.
• Track the designation choice on Schedule 3 of the T1 in the year the property is sold or deemed-sold.

The arithmetic is reasonably mechanical but easy to get wrong. The CRA exempt formula is: (1 + number of years designated as principal residence) ÷ (number of years owned) × total capital gain. The "+1" is a quirk of the formula that occasionally lets a household claim full exemption on a second property when only some of the years overlap.^[3]

For most Canadian couples with a city house and a cottage, the city house usually carries the higher annual appreciation in dollar terms and is the natural choice for most years. Re-running the numbers on each death gives the executor a chance to refine the allocation for the deceased's final return.

Probate is a provincial process — and properties in a second province compound that #

Real estate is governed by the law of the province where it physically sits.

The compounding effects:

• Two or more probate filings. Each province has its own forms, its own court fees, and its own processing timeline. Ontario's estate administration tax under the Estate Administration Tax Act runs at roughly 1.5% above $50,000 of estate value (calculated on Ontario-situs assets);^[4] other provinces have their own fees, ranging from $0 in Manitoba to high four figures in Nova Scotia for a similar value. See our probate fees across Canada breakdown.
• Two or more sets of executor work. Different lawyers (typically), different bank rules, different land-titles offices.
• Reciprocal recognition. Some provinces will "reseal" a probate certificate from another province without re-issuing it from scratch (this is faster and cheaper). Others require a full ancillary probate.
• Multiple wills strategy. Some Canadians with significant assets in multiple provinces execute multiple wills — one per jurisdiction — to allow each property to probate locally without dragging the entire estate through every province. This is a structurally complex move and should be done with a Canadian estates lawyer.

For an executor planning the work, the practical first step is to list every property by province, then call a local lawyer in each province to confirm the probate route. Our pillar what is probate in Canada walks the underlying process.

US-situs real estate adds the US estate tax regime #

A Canadian who owns US-situs real estate — a Florida condo, an Arizona winter home, a New York pied-à-terre — owns property that is subject to US federal estate tax on death, regardless of the owner's Canadian citizenship or residence. The IRS treats the value of US-situs assets owned by a non-US person as taxable in the deceased's US estate.^[6]

The Canada-US Tax Treaty mitigates this exposure significantly:

• The treaty allows Canadians to claim a pro-rata share of the broader US unified credit (the credit that effectively shelters very large US estates from federal estate tax).^[5]
• The pro-rata share is based on the ratio of US-situs assets to the deceased's worldwide gross estate.
• For Canadians with worldwide estates well below the US unified credit threshold (which is in the multi-million-dollar range, indexed annually), the pro-rata credit often eliminates the US estate tax.
• For larger Canadian estates, the pro-rata credit may shelter only a portion of the US-situs value, leaving a US estate tax bill payable.

Canadians with US-situs real estate should generally:

• Track the property's US fair market value annually and the deceased's projected worldwide estate.
• Consider holding the property through a Canadian or hybrid structure if the projected exposure is material.
• Coordinate with both a Canadian and a US tax advisor before any restructuring.

The Canadian deemed-disposition rule applies to the same property in parallel — the US estate tax does not displace it. Both regimes can hit the same asset, with foreign tax credits available in some circumstances to mitigate double taxation.

The cottage problem in particular #

The family cottage is the multi-property scenario most Canadian families discuss directly. Three options for cottage succession at death:

1. Leave it jointly to multiple children. Simple in the will, complicated in practice. Joint ownership often produces friction (who pays for repairs, who books which weekends, whose grandchildren get priority). The first time one child wants to sell and the other does not, the structure breaks down.
2. Leave it to a family trust during life or via the will. A discretionary family trust can hold the cottage with the children as beneficiaries, with rules about use, contributions, and eventual sale. Adds complexity and the 21-year trust rule, but solves some joint-ownership friction.
3. Leave it to one child with offsetting cash to the others. Often the cleanest option when one child uses the cottage substantially more than the others, funded with life insurance to balance the inheritances.

Our family cottage estate planning piece walks each option in detail.

Funding the capital gains tax bill #

Every property in the estate that does not qualify for the principal residence exemption triggers a deemed-disposition capital gains tax at death. For a household with one principal residence, one cottage, and one rental, two of those three are exposed. The exposure compounds in larger estates.

Only 50% of the resulting capital gain is included in taxable income — the standard inclusion rate, unchanged as of 2026 after a proposed increase to two-thirds was announced in 2024 and later cancelled — taxed at the deceased's marginal rate on the final T1 return. That is a meaningful cushion, but on a large, long-held property it can still mean a six-figure tax bill.

Three common funding approaches:

• Life insurance on the property owner, sized to the projected total capital gains tax across the portfolio. Predictable, cheap in earlier years, arrives tax-free in the estate.
• Sale of one or more properties by the executor to generate cash. Often the simplest if no beneficiary wants the property; emotionally hard if the property has sentimental value.
• Children refinance an inherited property to extract enough cash to settle the estate's tax bill while keeping the property.

The choice should be made years before death rather than reactively at death. Our companion piece on rental property estate planning walks the funding question in more detail.

The will and the executor mechanics #

A multi-property will should generally:

• List each property explicitly, either by specific bequest or as part of a clear residue allocation.
• Address the tax burden — for each property, specify whether the tax flowing from that property's deemed disposition is paid from the property itself or from the residue.
• Give the executor power to sell, mortgage, or otherwise deal with each property as needed.
• Address the principal residence designation in a way the executor can implement — often by giving the executor discretion to optimise across the portfolio.
• Reference any life insurance intended to fund the tax bill, with the policy number and insurer.

The executor's work on a multi-property estate is generally heavier than the will-drafting effort suggests. Each property needs its own valuation, its own clear title check, its own province-specific probate (if applicable), its own tax-base reconstruction, and its own listing or transfer. Most multi-property estates take 12 to 24 months to fully administer. Our executor of will checklist Canada walks the broader executor sequence.

What we focus on at It's Simple Will #

It's Simple Will captures the structural will and the practical "where is each property" map an executor will need. The Life Discovery Kit records each property's address, the mortgage status, the cost-base records, prior principal residence designations, any CCA history for rentals, the location of insurance policies, and the local lawyer or property manager for each. For a multi-property household, this map is often the single most valuable document the estate will produce.

The Will Creator handles the will side, including specific bequests of property, tax-burden allocation, and executor powers. The substantive planning decisions — principal residence allocation, ownership structures, US exposure — generally require a Canadian tax accountant in parallel. The two together produce a multi-property plan that survives the executor's first month of work.
