Can you buy a house with a friend in Canada?

Yes. Canadian law allows any number of people to purchase a home together, whether they are spouses, family members, friends, or business partners. You will need to choose between joint tenancy and tenancy in common ownership, and a co-ownership agreement is strongly recommended.

How does co-buying affect mortgage qualification?

Both (or all) buyers incomes and debts are combined for the mortgage application. This can significantly increase your purchasing power. However, all parties are jointly liable for the full mortgage — if one person stops paying, the others must cover the entire amount.

What happens if a co-buyer wants to sell?

This depends on your co-ownership agreement. Without one, a co-owner can force a sale through a court-ordered partition sale, which is expensive and time-consuming. A good co-ownership agreement outlines buyout procedures, right of first refusal, and dispute resolution.

Why Co-Buying Is Growing in Canada

With average home prices exceeding $700,000 nationally and $1 million+ in Toronto and Vancouver, co-buying has become a practical strategy for Canadians priced out of the market individually.

Scenario	Average Home Price	Income Needed (Single)	Income Needed (Co-Buying, 2 People)
National average	$713,000	~$145,000	~$72,500 each
Toronto	$1,080,000	~$215,000	~$107,500 each
Vancouver	$1,170,000	~$230,000	~$115,000 each
Ottawa	$640,000	~$130,000	~$65,000 each
Calgary	$580,000	~$120,000	~$60,000 each

Ownership Structures for Co-Buyers

Joint Tenancy vs. Tenancy in Common

Feature	Joint Tenancy	Tenancy in Common
Ownership share	Equal (50/50, 33/33/33, etc.)	Can be unequal (60/40, 70/30, etc.)
Right of survivorship	Yes — your share passes to co-owner(s) on death	No — your share passes to your estate/heirs
Can sell your share independently	No (must sever tenancy first)	Yes (can sell or transfer your share)
Best for	Married/common-law couples	Friends, siblings, investors, unequal contributions
Transfer to heirs	Automatic (bypasses will)	Through your will or estate

For co-buyers who are not romantic partners, tenancy in common is almost always the better choice because it allows unequal ownership, independent transfer, and estate planning flexibility.

Income	All buyers’ incomes combined

Combined	$140,000	—	~$700,000
