The client
A couple who landed in Windsor, Ontario fourteen months before applying, with the primary applicant employed in the region's auto sector on a T4 and a spouse working part-time. Neither had a Canadian credit bureau file with enough history to score — a routine situation for first-time buyers who are also newcomers, and one CMHC's own underwriting notes make explicit room for.

The problem
The obstacle here was never income or ratios — it was that neither applicant had enough Canadian credit history to produce a usable bureau score. CMHC's own underwriting guidance leaves room for exactly this, noting it will consider “alternative methods of establishing creditworthiness for borrowers without a credit history,” but a lender still has to build that file from documents rather than pull it from a bureau.
What stood in for a bureau score
- ▸Twelve consecutive months of rent payments, verified through bank statements and a landlord letter
- ▸Twelve months of utility payment history on the same address
- ▸A car loan, opened since arrival, beginning to build a conventional Canadian file alongside the alternative sources
None of it is a substitute for time — a bureau score will eventually exist on its own — but it was enough, assembled carefully, to satisfy an insurer used to seeing exactly this pattern from newcomer files.
The numbers
Once the credit question was answered, the ratio math was straightforward and comfortable. At 10%, the down payment here sat above what most newcomer files show in the national down payment statistics, which gave the file some cushion before the ratios were even run.
| The insured loan | Amount |
|---|---|
| Purchase price | $378,000 |
| Down payment (10%) | −$37,800 |
| Base mortgage (90% LTV) | $340,200 |
| CMHC premium at 3.1% (85.01–90% LTV band) | +$10,546 |
| Total insured mortgage | $350,746 |
| Ratio check at the qualifying rate | Figure |
|---|---|
| Combined income ($5,100 + $2,200) | $7,300/month |
| Minimum qualifying rate on a 4.69% contract rate | 6.69% |
| Payment at the qualifying rate, 25 years | $2,390/mo |
| GDS (payment + $290 tax + $130 heat) ÷ income | 38.5% |
| TDS (GDS numerator + $310 car loan) ÷ income | 42.7% |
38.5% and 42.7% sit inside CMHC's 39% GDS and 44% TDS maximums with only modest room — a reminder that alternative credit answers the qualification question, not the affordability one; the income still has to carry the payment.
The land transfer tax refund
As first-time buyers who had never owned a home anywhere in the world, the couple qualified for Ontario's land transfer tax refund — up to $4,000, enough to cover the tax in full only on homes at or under $368,000.
| Land transfer tax on $378,000 | Amount |
|---|---|
| Gross Ontario land transfer tax | $4,145 |
| First-time-buyer refund (maximum) | −$4,000 |
| Net land transfer tax owing | $145 |
The solution
An FSRA-licensed Ontario mortgage agent built the credit file from documents rather than treating the lack of a bureau score as a dead end.
First, assembled twelve months of alternative credit sources. Bank statements showing rent paid on the same date every month, a landlord letter confirming the tenancy and payment history, and utility statements covering the same window.
Second, matched the file to an insurer and lender with a published newcomer program. Not every lender's underwriting accepts alternative credit the same way; the file went to one whose program explicitly covers it.
Third, let the car loan do double duty. Opened months earlier and paid on time since, it gave the file its first piece of conventional Canadian credit history alongside the alternative sources — useful now, and the start of a bureau file for next time.
The outcome
Approved and funded: insured at 90% LTV, with GDS at 38.5% and TDS at 42.7%. The couple's alternative credit history, combined with a car loan already reporting on time, carried the file the way a conventional bureau score would have for anyone else.
The $145 net land transfer tax, plus legal fees and adjustments, was the only cash due at closing beyond the down payment; Ontario's RST on the default-insurance premium added a separate $844 in cash, since the tax on the premium cannot be added to the mortgage.
What to take from this file
- 01No Canadian bureau score is not the same as no creditworthiness. CMHC's own guidance makes room for alternative methods when a borrower simply has no history to score.
- 02Assemble alternative credit the way a bureau file is assembled — in months, not anecdotes. Twelve consistent months of rent and utility payments, documented from bank statements, is what makes the case.
- 03Not every lender's alternative-credit policy is the same. The sources and number of months accepted vary by lender and insurer; match the file to one with a published newcomer program.
- 04A first-time buyer refund can erase most or all of the land transfer tax. On this file it cut $4,145 owing down to $145 — but only up to the $4,000 maximum, and only up to the $368,000 full-coverage threshold.
- 05Start building conventional credit immediately, even while relying on alternative sources. The car loan on this file will make the next mortgage, or the next credit decision, considerably easier.
