Federal government eases Canada's mortgage insurance rules for select new housing construction

Building a triplex or fourplex could become easier to finance under mortgage insurance changes announced in Prime Minister Mark Carney’s 2026 federal budget today.

The Government of Canada plans to remove the $1.5-million property value ceiling and the requirement for owners to live in one of the homes for eligible new triplexes and fourplexes.

Additionally, private mortgage insurers would also be allowed to cover loans for multi-unit residential properties with five to 50 units.

Both changes — intended to help realize the construction of new “missing middle” homes — will apply to mortgage insurance applications submitted by lenders on or after Feb. 1, 2027, with the aim of helping smaller builders finance more housing.

Mortgage insurance protects lenders if borrowers fail to repay. It also helps borrowers obtain financing with less money upfront.

Generally, a multiplex is a small residential building or development containing several self-contained homes — each with its own kitchen, bathroom, and living space. A triplex contains three homes, while a fourplex contains four units. Such developments — with units configured side by side, stacked vertically, or a combination of both –can be found on small properties, including single-family lots.

For new triplexes and fourplexes, insured loans could cover up to 90 per cent of the property’s expected value upon completion. This would apply to both construction and purchases of newly completed properties.

The budget shows the change with a hypothetical $3-million fourplex, which exceeds the current $1.5-million insurance limit. Under the new rules, an eligible builder could theoretically obtain an insured loan of up to $2.7 million.

Once finished, the builder could rent out all four homes with an insured mortgage repaid over up to 30 years or sell the homes to individual buyers.

Borrowers would still need to qualify. For mortgages on completed triplexes and fourplexes, housing costs could not exceed 39 per cent of gross income, while total debt payments could not exceed 44 per cent. Mortgage stress test requirements would also apply, and at least one borrower or guarantor would need a credit score of 600 or higher at approval.

For properties with five to 50 homes, private insurers could cover construction, purchases, refinancing, and mortgage renewals, without a property value ceiling or a requirement for owners to live on-site.

Loans could cover up to 90 per cent of the property’s value for new construction, with mortgage repayment periods of up to 50 years. For other loans, the limits would be 85 per cent and 40 years. Separate rules would apply to construction loans themselves.

Each home would need its own cooking, sleeping, and bathroom facilities. The property must have a single legal title or ownership structure; separately titled properties could not be bundled together simply to meet the required number of units.

Borrowers would need a net worth of at least 25 per cent of the requested loan, and no less than $100,000, calculated using their assets held in Canada.

The building’s income after operating expenses must also cover at least 115 per cent of its debt payments for a five-year mortgage term, or 110 per cent for a 10-year term.

For construction loans under both sets of changes, the specified repayment-period limits and debt-payment requirements would not apply. Insurers would instead use their own criteria to assess borrowers’ ability to repay.

The changes address a financing hurdle that has persisted even as Canada’s municipal governments allow more homes on single-family lots and other low-density zoning.

The federal government’s Spring 2026 economic update, which first hinted at these forthcoming mortgage insurance policy changes, acknowledged that builders still struggled to borrow at rates that made smaller projects viable. Traditional lenders often treat multiplexes as commercial developments — requiring larger upfront contributions and stricter qualifications that can make projects financially unfeasible.

Broader access to insured loans could reduce the money eligible builders need to contribute upfront and expand their financing options. Removing the property value ceiling could also help projects in expensive housing markets qualify, while dropping the live-in requirement would allow builders to use this financing for triplexes and fourplexes intended entirely for rental housing.
