Do you pay capital gains on an inherited house in Ontario?

Tax rules turn on the estate’s specific facts. Everything below is general information drawn from CRA guidance, pending review by the estate’s accountant. Get professional advice before filing anything.

The day someone dies, the tax system sells their house

Canada has no inheritance tax. What it has instead is deemed disposition: immediately before death, the deceased is treated as having sold all capital property, including the home, at fair market value. If the home was their principal residence for every year of ownership, the principal residence exemption generally shelters that gain in full, and the estate’s terminal return reports it tax-free. If it was a cottage, a rental, or only partly sheltered, the gain to death is taxed on the terminal return, paid by the estate, not the beneficiaries.

That date-of-death fair market value matters twice over. It is the number the terminal return uses, and it becomes the estate’s cost base for everything that happens afterward. It is also auditable: the Estate Information Return declares values the Ministry of Finance can cross-reference against MPAC. A documented, defensible valuation of the home at death is not paperwork for its own sake; it is the anchor for every tax filing that follows.

The part that catches executors: the gain after death

The principal residence exemption generally stops at death. Once the home is estate property, nobody is living in it as a principal residence, and appreciation from the date of death to the eventual sale is typically a taxable capital gain to the estate. The inclusion rate is 50 percent; the proposed 66.67 percent increase was cancelled in March 2025. A qualifying Graduated Rate Estate can pay tax on that gain at graduated rates for up to 36 months after death, which is worth real money and real planning.

The practical takeaway is simple and honest: the longer a vacant estate home is held, the more post-death gain can accrue, and that gain is the estate’s to pay tax on. Selling sooner limits the taxable post-death gain, on top of ending the carrying costs. That does not mean panic-selling into a lowball offer; it means running the sale with intent instead of drift. See the three-way comparison and how to use the probate wait so the home lists the day it legally can.

What to hand the accountant

Three things make the estate’s tax work clean: a documented fair market valuation of the home at the date of death, records of every carrying and selling cost from death to closing, and the final sale figures. If a pre-sale renovation is part of the plan, its documented costs belong in that file too. That paper trail serves double duty, because the same record that satisfies CRA is the record that shows beneficiaries the estate trustee maximized value.
