The family cottage is often a family’s most emotionally significant asset and biggest estate planning challenge — decades of appreciation, no cost base for repairs, and children who may disagree about what happens to it.
Cottage capital gains: illustrative examples
| Scenario | Purchase year | Purchase price | Improvements | FMV at death | Gain | Est. tax |
|---|---|---|---|---|---|---|
| Muskoka cottage (no records) | 1985 | $75,000 | $20,000 | $800,000 | $705,000 | ~$150,000+ |
| PEI shore cottage | 1992 | $120,000 | $80,000 | $600,000 | $400,000 | ~$87,000 |
| BC waterfront lot | 2005 | $350,000 | $150,000 | $1,200,000 | $700,000 | ~$155,000 |
| PRE-sheltered (20 of 35 years) | 1990 | $100,000 | $50,000 | $700,000 | $550,000 × (21/36) | ~$67,000 |
Estimates at combined federal/Ontario marginal rate; 2026 50% capital gains inclusion rate. Actual tax depends on other income.
Four cottage succession strategies compared
| Strategy | Capital gain triggered when | Probate bypass | Control retained | Complexity |
|---|---|---|---|---|
| Leave to estate (no planning) | At your death | No | Yes (during life) | None |
| Direct gift to children now | Immediately on transfer | Yes | No | Low |
| Family trust | On transfer to trust | Yes | Yes (as trustee) | High |
| Life insurance to fund tax | At your death (tax funded) | Insurance yes; cottage no | Yes | Moderate |
| Multiple wills (cottage in secondary) | At your death | Yes (secondary will not probated) | Yes | Moderate |
The ACB documentation checklist
Keep receipts and invoices for all of the following (anything permanently added to the property):
- Original purchase price and closing costs
- Legal/notarial fees at purchase
- Addition of any permanent structure (boathouse, garage, bunkie, addition)
- Shoreline/dock installation or rebuild
- Septic system installation or replacement
- Well drilling
- New roof, siding, foundation work
- New heating system (furnace, heat pump, propane)
- Major kitchen or bathroom renovations
- Electrical panel upgrades
- Permanent survey costs
- Capital land improvements (clearing, grading, road access)
Cottage co-ownership agreement: key provisions
If multiple siblings will co-own the cottage (by inheritance or by design):
- Usage scheduling — annual rotation or booking system
- Maintenance cost sharing — proportionate to ownership shares
- Governance for capital decisions — majority vote threshold
- Buy-out mechanism — first right of refusal, appraisal process
- Forced sale provision — timelines and pricing for partition
- Bring-guest and rental rules — short-term rental of cottage by one sibling requires unanimous consent, or not?
Options for passing on a cottage
1. Leave it in your will (simplest, but triggers taxes)
The cottage passes to heirs per your will. A deemed disposition at fair market value on death triggers capital gains tax on the estate, reduced by any capital improvements and the principal residence exemption (if available — can only be applied to one property).
2. Gift it during your lifetime
You can transfer the cottage to children now. This triggers a deemed disposition at fair market value and capital gains tax immediately. Gifting can be useful if the cottage has low gains and children want to use it — but it gives up control and accelerates the tax hit.
3. Transfer to a family trust
A family trust (discretionary trust) can hold the cottage, distributing income and gains among family members to minimize total tax. The trust must file annual T3 returns and has a 21-year deemed disposition rule (capital gains triggered every 21 years). Trusts are more complex but can be effective for high-value properties.
4. Life insurance to fund the tax
Buy a life insurance policy (whole life or term-to-100) sized to cover the estimated capital gains tax on the cottage at death. The proceeds pay the tax bill, allowing heirs to keep the property without a forced sale.
Frequently asked questions
Can we claim the principal residence exemption on a cottage? Only if the cottage was your family’’s “ordinarily inhabited” principal residence for those years. A family can designate only one property per year as its principal residence. If you have been claiming the exemption on your city home, the cottage has been accumulating a taxable gain since purchase.
What is the capital gains inclusion rate on cottage sales in 2026? For individuals, the capital gains inclusion rate is 50% on the first $250,000 of annual gains and 2/3 on gains above $250,000. For trusts, the 2/3 rate applies to all gains. Many long-held cottages have significant unrealized gains — planning ahead with professional tax advice is critical.
Do all siblings have to agree to sell the cottage? Under tenants-in-common ownership, any co-owner can apply to court for a partition and sale if the other owners refuse to cooperate. This is expensive, slow, and emotionally destructive. A well-drafted co-ownership agreement with a buy-sell mechanism is the best way to avoid this outcome.
Estimating the cottage tax bill
Use this simplified formula to estimate the estate’’s capital gains exposure:
Capital gain = (Fair market value at death) − (Purchase price + capital improvements)
Then apply:
- First $250,000 of gain: 50% inclusion rate × your marginal rate
- Gain above $250,000: 66.67% inclusion rate × your marginal rate
Example: Cottage bought in 1990 for $120,000. Current FMV: $850,000. Capital improvements: $80,000.
- Gain = $850,000 − $120,000 − $80,000 = $650,000
- Tax (approx. 43% marginal rate): $250,000 × 50% × 43% + $400,000 × 66.67% × 43% ≈ $168,000
A $500,000 life insurance policy would more than cover this bill — and the premium cost is typically far less than the tax owing.
