What are the capital gains consequences when a family cottage is inherited?

When you die owning a cottage or vacation property, CRA deems you to have sold it at fair market value on the date of your death — even though no actual sale occurred. This is called deemed disposition. The capital gain is calculated as: fair market value at death minus your adjusted cost base (ACB — original purchase price plus capital improvements). Example: cottage purchased in 1988 for $80,000; current fair market value $750,000; capital improvements of $60,000. ACB = $140,000. Gain = $750,000 − $140,000 = $610,000. Taxable capital gain = $610,000 × 50% (inclusion rate) = $305,000. Tax owing at 43.7% (combined federal/Ontario marginal rate on $305,000 gain added to other income) ≈ $133,000 of terminal tax from the cottage alone. Your estate must have $133,000 of cash to pay CRA — or the cottage must be sold.

Can I use the principal residence exemption to eliminate cottage capital gains?

Yes — but with important limits. The principal residence exemption (PRE) can shelter all or part of the cottage capital gain if the cottage qualifies as your principal residence for the years you designate. Rules: (1) You can only designate one property as principal residence per family unit per year (family unit = you, spouse, and minor children). (2) For years you designate the cottage as your principal residence, those years are sheltered. For years you designate your city home, the cottage gains for those years are not sheltered. (3) The "one plus" rule helps: PRE formula = (years designated as PR + 1) ÷ total years owned × total gain. The "+1" is a gift from the government. Practical strategy: if you have two properties and plan to sell one, consider designating the years with the highest annual capital gain to the property you are selling. For many Canadians with long-owned cottages, a combination of PRE years and ACB improvements can significantly reduce — but rarely eliminate — decades of accumulated gain on a highly appreciated property.

What is a family trust for cottage planning and how does it work?

A family trust (inter vivos discretionary trust) can hold the cottage during your lifetime and distribute the beneficial interest to family members, which accomplishes several goals: (1) Probate bypass — trust assets do not flow through your estate on death; the cottage passes per trust terms without probate. (2) Income splitting — if the trust earns rental income from the cottage, that income can be allocated to adult family members in lower tax brackets. (3) Gradual capital gains transfer — when the cottage is transferred to a trust, a deemed disposition occurs at fair market value at the time of transfer, triggering the gain immediately at your rates. However, you can then elect to use the PRE to shelter those years of gain before transfer. (4) After the transfer: the trust holds the cottage; adult beneficiary family members may be able to use the PRE on their own share of any future gain from the trust (subject to a complex allocation process). Important: the trust has a 21-year deemed disposition rule — CRA deems all trust assets sold at fair market value every 21 years. Planning must account for this event.

Should I give the cottage to my children now or leave it in my estate?

Gifting the cottage now vs. at death is one of the central decisions in cottage succession planning. Giving now (inter vivos transfer): triggers a deemed disposition at current FMV today; capital gain is paid now at current rates; children acquire the cottage at their new ACB (current FMV) — minimizing future capital gains for them; you give up ownership and control; if the cottage appreciates significantly, your children benefit from all future appreciation at their lower cost base. Leaving in estate (testamentary transfer): deemed disposition at FMV at date of death; gain is reported in your terminal return; potentially large tax bill at death from decades of accumulated appreciation; children inherit at FMV at date of death — their future gains are only on appreciation after your death. In most cases: gifting to a family trust (rather than directly to children) provides the flexibility of an inter vivos transfer while maintaining flexibility over who uses the cottage and when distributions occur. Gifting directly to children eliminates your ability to control or reclaim the property.

What is the "island in a trust" (cottage in a trust) strategy?

The "island in a trust" strategy refers to transferring a vacation property (cottage, island, recreational land) into a family trust as a way to: isolate the property from your personal estate (avoiding probate); begin the clock on the 21-year trust rule at a time of your choosing; allow adult children to eventually be designated as beneficiaries who can use the PRE on their share of future gains; manage control and succession among multiple children without forcing an immediate ownership decision. How it works in practice: (1) You create a trust (you and/or your spouse as initial trustee). (2) You transfer the cottage to the trust — this triggers a deemed disposition at current FMV. You pay capital gains tax on the gain from original ACB to current value, which may be reduced by PRE years. (3) Your children become discretionary beneficiaries. (4) The trust holds and manages the cottage; the trustee can rent it, make improvements, and ultimately distribute it. (5) Before the 21-year deemed disposition, the trust either distributes the property to beneficiaries (who may use their PRE) or sells it and distributes proceeds. This strategy requires careful tax and trust law advice and involves upfront capital gain recognition.

How do I increase the adjusted cost base (ACB) of my cottage to reduce capital gains?

Your ACB directly reduces your capital gain — every dollar of ACB is a dollar of gain you do not pay tax on. ACB includes: the original purchase price; all legal/notarial fees at acquisition; real estate commission at purchase; all capital improvements made over the years (permanent additions, renovations, foundation work, major appliances considered fixtures, a new dock, a new roof). ACB does NOT include: operating expenses (maintenance, repairs, utility costs, insurance); vacation costs and travel to the cottage; routine upkeep. Documentation required: receipts for all improvements — often spanning decades. Common issue: Canadians who bought cottages in the 1970s–1990s may lack records of improvements. CRA allows a reasonable estimate if supported by evidence, but receipts are far more defensible on audit. Recommendation: start a Capital Improvements Ledger today — document every significant expenditure with a brief description, date, cost, and receipt. A $200,000 accumulated ACB on a cottage you paid $100,000 for in 1985 can reduce your capital gain by that full $200,000, saving approximately $40,000–$50,000 in tax.

What happens to the cottage when multiple siblings inherit it together?

Inheriting a cottage with two or more siblings (as either joint tenants or tenants in common) creates a co-ownership situation that frequently produces conflict. Common issues: (1) One sibling wants to sell; another wants to keep — without agreement, either party can apply to court for partition and sale (forced sale at sometimes distressed value). (2) Unequal use and unequal maintenance contribution — who pays for the dock repair when sibling B never comes? (3) Capital gains on eventual sale — each sibling has their own ACB based on the inherited FMV. The solution: a cottage co-ownership agreement (establish at the time you inherit, not years later after grievances accumulate). The agreement should specify: usage scheduling; maintenance cost sharing; buy-out provisions if one sibling wants to exit; forced sale process and pricing mechanism; governance for major capital decisions. Estate planners often recommend leaving the cottage to only one child in the will with an equalization strategy (life insurance or additional investment assets) for other children — avoiding co-ownership conflict entirely.

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?
