A Canadian real-estate investor is taxed on net rental income — gross rent minus deductible expenses — and on the capital gain when a property is sold, with 50% of that gain included in income. But two rules change the picture more than investors expect: Capital Cost Allowance (CCA) cannot create or increase a rental loss, and since January 1, 2023 the property-flipping rule treats the gain on a housing unit owned for fewer than 365 consecutive days as fully taxable business income rather than a capital gain. This guide explains how rental income, CCA, the principal residence exemption, GST/HST and the flipping rule fit together for Alberta and BC investors.
How rental income is taxed
Rental income is reported on a net basis: you take gross rent received and subtract the expenses incurred to earn it — mortgage interest (not principal), property tax, insurance, utilities you pay, repairs and maintenance, condo fees, advertising and reasonable management fees. The remaining net rental income is added to your other income and taxed at your marginal rate. Source: T4036, Rental Income — Canada.ca.
The single biggest planning point for landlords is Capital Cost Allowance.
CCA: the deduction that cannot create a loss
CCA is the tax version of depreciation. You may claim CCA on the building (land is never depreciable) to reduce taxable rental income. The critical limit: CCA on a rental property cannot be used to create or increase a rental loss. If your rental operation is already at break-even or a loss before CCA, you cannot use CCA to push it further into the red. Source: Rental income — Capital cost allowance — Canada.ca.
CCA is also discretionary — you choose how much to claim each year, up to the class maximum — and when you eventually sell, previously claimed CCA can be recaptured into income. That trade-off is why many investors model CCA over the full hold, not year by year.
The principal residence exemption and mixed use
The principal residence exemption (PRE) can shelter the capital gain for the years a property genuinely was your principal residence. A property bought purely as an investment generally does not qualify. Where a home is part-rented or used partly for business, the math gets detailed — and claiming CCA on a portion of a home can jeopardize principal-residence status for that portion, converting part of an otherwise tax-free gain into a taxable one.

The property-flipping rule (since January 1, 2023)
This is the rule that most reshapes investor tax. For dispositions on or after January 1, 2023, the gain on a flipped property — a Canadian housing unit you owned for fewer than 365 consecutive days — is fully taxable as business income. It is not treated as a capital gain (so the 50% inclusion does not apply), and the principal residence exemption is not available. Source: Residential property flipping rule — Canada.ca.
Statutory life-event exceptions can take a sale outside the rule even within 365 days, including:
- death of the owner or a related person;
- a person joining the household (e.g., a new child, or an elderly parent);
- a breakdown of marriage or common-law partnership (generally living apart 90+ days);
- a threat to personal safety;
- the owner's or a related person's serious disability or illness;
- an eligible relocation for work;
- an involuntary termination of employment;
- insolvency; and
- destruction or expropriation of the property.
Outside these exceptions, holding under a year means business-income treatment — a result investors timing a quick resale need to plan around.
A separate BC rule: the provincial home-flipping tax
British Columbia has introduced its own provincial home-flipping tax, effective January 1, 2025. It is distinct from the federal 365-day rule and applies under its own provincial framework. An Alberta or BC investor selling a recently acquired BC property should treat the two as independent tests rather than a single rule — the federal rule can apply, the provincial BC tax can apply, and they are assessed separately.
GST/HST on the sale
GST/HST treatment turns on what is being sold. New or substantially renovated residential housing is generally taxable; a used, previously occupied residential resale is generally exempt; and commercial real property is generally taxable. Source: GST/HST memorandum 19-1, Real Property and the GST/HST — Canada.ca.
The line between a renovation and a substantial renovation, and between residential and commercial use, decides whether tax applies — so confirm the treatment before a deal closes, not after.
How RN Canada helps
RN Canada advises Alberta and BC real-estate investors on the calls that move the after-tax number: structuring net rental income, modelling CCA and recapture across the hold, protecting principal-residence status on mixed-use homes, and checking the federal property-flipping rule and the separate BC home-flipping tax before a quick resale. Our bookkeeping and tax filing service keeps rent, expenses and CCA tracked cleanly across every property, and a fractional CFO brings senior structure once one rental becomes a portfolio. See our real estate and property industry page for the full picture.

Frequently asked questions
Rental income is taxed on a net basis — gross rent minus deductible expenses such as mortgage interest, property tax, insurance, repairs and management fees. You may claim Capital Cost Allowance on the building, but CCA on a rental property cannot create or increase a rental loss. Keeping clean records of rent and deductible expenses, and applying CCA correctly, is the core of getting rental tax right.
For dispositions on or after January 1, 2023, the gain on a flipped property — a Canadian housing unit you owned for fewer than 365 consecutive days — is fully taxable as business income, not a capital gain, and the principal residence exemption does not apply. Statutory life-event exceptions exist for events such as death, disability or serious illness, separation, a new child, a work relocation, involuntary job loss, insolvency, a threat to personal safety, or destruction or expropriation.
The principal residence exemption can shelter the capital gain for the years a property genuinely was your principal residence. A property bought and held purely as an investment generally does not qualify. Claiming CCA on a portion of a home can also jeopardize principal-residence status for that portion, so mixing personal use and rental use needs careful planning before, not after, a sale.
It depends on the property. New or substantially renovated residential housing is generally taxable for GST/HST, a used (previously occupied) residential resale is generally exempt, and commercial real property is generally taxable. A builder selling a new unit and an owner reselling a used home are treated very differently, so the treatment should be confirmed before a transaction closes.
They are two separate rules. The federal property-flipping rule treats the gain on a unit held under 365 days as business income for dispositions on or after January 1, 2023. British Columbia has its own provincial home-flipping tax, effective January 1, 2025, which is distinct from the federal 365-day rule. An Alberta or BC investor selling a recently acquired BC property should check both, because they apply independently.
