Family Cottage Trust Structures in Canada

Last updated May 24, 2026 · 3 min read
Quick answer
A trust can hold the family cottage to keep it out of probate and manage succession across generations, but the tax catches are significant. Alter ego and joint partner trusts (age 65+) let a cottage roll in at cost and avoid probate; ordinary family trusts trigger a gain on funding. Most family trusts can no longer claim the principal residence exemption, so a long-held cottage's gain is fully exposed — and the 21-year deemed-disposition rule can crystallize that gain inside the trust.

Families who are determined to keep the cottage forever often hear that the answer is "put it in a trust." A trust can indeed hold a cottage, keep it out of probate, and set the rules for how the next generation shares it. But a cottage in a trust collides with three tax features that make this one of the more nuanced structures in Canadian estate planning — the funding tax, the lost principal residence exemption, and the 21-year rule. Used in the right case it is powerful; used reflexively it can create more tax than it saves.

This guide explains cottage trust structures and their catches. It is general information, not advice; this is specialist tax and legal territory.

Why use a trust for a cottage

A trust can hold the cottage outside probate, govern how the next generation shares and maintains it under set rules, and provide some creditor or family-law protection. For a family resolved to keep a property intact across generations, a trust offers a level of control that a simple gift in a will does not.

Which trust

For probate and succession, the usual vehicles are alter ego and joint partner trusts (age 65+), because the cottage can transfer in at cost without triggering a gain.[3] A discretionary family trust is also used, but funding it with an appreciated cottage is a deemed disposition — a capital gain on the way in. So the funding tax alone often steers families toward the 65+ trusts or away from trusts entirely.

The principal-residence catch

This is the catch most people miss. Since 2017, most ordinary family trusts can no longer claim the principal residence exemption.[2] A cottage that, held personally, could have been designated a principal residence to shelter its gain generally loses that shelter inside such a trust — exposing the full gain. Certain trusts (alter ego, qualifying spousal, and some trusts for minors or disabled beneficiaries) retain limited access, but the general rule is a real drawback that requires specific advice.

The 21-year rule

Layered on top, the 21-year rule can crystallize the cottage's accrued gain inside the trust every 21 years, even though nothing is sold,[1] because most trusts face a deemed disposition of capital property on that cycle (alter ego/joint partner trusts are timed to a death instead). For a cottage that appreciates steadily across generations, this periodic tax is a serious factor — see the 21-year rule.

When it fits — and the simpler alternatives

A cottage trust can make sense for a high-value, multi-generational cottage, a blended family, or a probate-heavy province where keeping the property intact justifies the cost and complexity. For most families, simpler tools are a better fit: leaving the cottage to one child with equalization, or to several children under a co-ownership agreement. See keeping the cottage in the family and cottage co-ownership agreements.

What we focus on at It's Simple Will

The Will Creator handles the will-based approaches that suit most cottage owners — a clear gift with equalization, and instructions for the property. A cottage trust is specialist work for a lawyer and accountant, and its tax catches mean it should be entered into with eyes open. For the broader strategy, see keeping the cottage in the family.

Frequently asked questions

Why hold a cottage in a trust?

To keep it out of probate, to manage shared use and succession across generations under set rules, and sometimes for creditor or family-law protection. A trust can hold the cottage after your death and govern how the next generation shares it, which appeals to families determined to keep a beloved property intact.

Which trust is used for a cottage?

For probate and succession planning, often an alter ego or joint partner trust (available from age 65), because the cottage can be transferred in at cost without triggering a gain. A discretionary family trust is also used, but funding it with an appreciated cottage is a deemed disposition that triggers tax on the way in.

What's the principal-residence catch?

Since 2017, most ordinary family trusts can no longer claim the principal residence exemption. So if a cottage that could have been your principal residence is held in such a trust, the exemption that might have sheltered its gain is generally lost, leaving the full gain exposed. Certain trusts (such as alter ego or qualifying spousal trusts) retain limited access — get advice.

How does the 21-year rule affect a cottage in a trust?

It can force a tax bill on the cottage's accrued gain every 21 years, even though nothing is sold, because most trusts face a deemed disposition of capital property on that cycle. For a cottage that appreciates steadily over generations, this periodic crystallization is a serious drawback to consider before using a trust.

Is a cottage trust worth it?

Sometimes — for a high-value, multi-generational cottage, a blended family, or a probate-heavy province where keeping the property intact justifies the cost and tax complexity. For many families, simpler tools (a clear will leaving the cottage to one child with equalization, or a co-ownership agreement) are a better fit.

What are the simpler alternatives?

Leaving the cottage to one child and equalizing the others with insurance or cash, or leaving it to several children under a co-ownership agreement. These avoid the trust's funding tax, 21-year rule, and principal-residence problem, and suit most families better than a trust. See our guides on keeping the cottage in the family.
