Capital gains on a Canadian rental sale — what you'll actually owe — Jul 22 2026 09:53 update
CRA treats rental income like a business — which means the deductions, forms, and pitfalls are business-grade too.
> _Topic: Canadian rental property capital gains tax_
What the rule actually says
The legal text is short. The provincial statute governing this topic is worth reading in full — most disagreements come from paraphrasing it instead of quoting it. Bookmark the actual government page and refer to it in every notice you send.
The mistake landlords make most often
The most common failure isn't malice — it's process drift. Templates get edited over time, notice periods shift by a few days, and small errors compound. A single quarterly review of your standard documents fixes 80% of the compliance risk.
What to do this week
Pull your current template and read it end to end.
Diff it against the latest official version from your province.
Update the date, references, and any section numbers that changed.
- Save the updated version as the new default for all new leases.
Documentation you must keep
The signed lease + amendments
Every rent receipt or ledger entry
Any correspondence that could be relevant to a future dispute
Photos of the unit at move-in and move-out
- Copies of every notice served, with proof of service
Bottom line
The landlords who avoid tribunal trouble are the ones who treat compliance as a habit, not an emergency. Fifteen minutes a month keeps you out of the ninety-minute hearing.

QWhat's the deadline to file rental income to the CRA?
Rental income is reported on the T776 form filed with your personal T1 return. The deadline is April 30 of the year after you earned the income (June 15 if you're self-employed, but any balance owing is still due April 30).
QDo I need to charge GST/HST on rent?
Long-term residential rent is GST/HST-exempt. Short-term rentals (under 30 days) are taxable once you exceed the $30,000 small-supplier threshold across all your business activities.
QCan I deduct mortgage payments?
You can deduct the interest portion (and most carrying costs) of your mortgage on a rental property, but NOT the principal repayment. Central Rentals splits this automatically inside your T776 export.
