The client
A self-employed general contractor in Tillsonburg applied for a $310,000 purchase at 5% down, weeks after filing their latest T1 return but before CRA had issued that year's Notice of Assessment.
Purchase price
$310,000, Tillsonburg

Net income, two years ago (assessed)

Net income, freshly filed (not yet assessed)

CRA had not yet issued a Notice of Assessment
The problem
A Notice of Assessment is CRA's own confirmation that a filed tax return has actually been reviewed -- and CRA can take weeks to issue one after a return is filed, longer during peak filing season.
What a rigid 'most recent NOA' policy could not distinguish
- ▸The contractor's T1 for the most recent tax year had been filed weeks earlier, in good faith and on time
- ▸CRA had not yet processed and issued that year's Notice of Assessment -- a normal processing lag, not a red flag about the return itself
- ▸The first lender's policy required 'the most recent Notice of Assessment' and, finding none for the freshly filed year, treated the file as though a document had gone missing rather than one that simply did not exist yet
The contractor had done everything correctly and on time. The file stalled on a document that no self-employed applicant filing this early in the season could ever produce.
The numbers
Averaging the two years CRA had already confirmed -- not the freshly filed, even stronger year -- is what the file actually needed to qualify.
| Qualifying on the two confirmed years | Amount |
|---|---|
| Two most recently assessed years, combined | $170,000 |
| Average annual net business income | $85,000 |
| Base mortgage (95% of purchase price) | $294,500 |
| CMHC premium (4.00% at 90.01-95% LTV) | +$11,780 |
| Total insured mortgage | $306,280 |
| Ratio check at the qualifying rate | Figure |
|---|---|
| Payment at the qualifying rate (6.85%), 25 years | $2,117/mo |
| GDS (payment + $305 tax + $120 heat) ÷ $7,083 income | 35.9% |
| TDS (GDS numerator + $245 car loan) ÷ $7,083 income | 39.3% |
35.9% and 39.3% sit comfortably inside CMHC's 39% GDS and 44% TDS maximums, in a range consistent with mortgage broker market share data for self-employed purchases -- on the two confirmed years alone. The freshly filed, higher year was never needed to clear the file, only to strengthen it further at a future renewal.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act separated what CRA had actually confirmed from what had simply not caught up yet.
First, supplied the filed T1 return and CRA's own electronic-filing confirmation as evidence the freshly filed year had been submitted in good faith and on time.
Second, built the qualifying income entirely from the two years already confirmed by their own Notices of Assessment, averaging $78,000 and $92,000 rather than waiting on CRA's processing timeline.
Third, moved the file to a lender willing to treat the freshly filed year as informational only, with a plan to add it at a future renewal once its own Notice of Assessment exists.
The outcome
The purchase funded insured at 35.9% GDS and 39.3% TDS on the two confirmed years alone, with the newer, even stronger year available to add at a future renewal once its own Notice of Assessment exists.
Both ratios sit comfortably inside CMHC's 39% GDS and 44% TDS maximums; the file was never short on income, only on a document CRA had not yet issued.
What to take from this file
- 01A Notice of Assessment that does not exist yet is not a missing document -- it is a processing timeline. CRA can take weeks to assess a freshly filed return.
- 02A rigid 'most recent NOA' policy is one lender's own practice, not a universal requirement. Confirm whether a specific lender will average the years already assessed instead.
- 03A filed T1 return plus CRA's own filing confirmation is real evidence of good-faith filing, even without an NOA yet attached to it.
- 04Don't wait on an unissued document when the confirmed years already qualify the file. Add the newer, stronger year at the next renewal instead.

- ▸OSFI — Minimum qualifying rate for uninsured mortgages — the minimum qualifying rate — greater of contract rate + 2% or 5.25%.
- ▸CMHC — CMHC Reviews Underwriting Criteria — GDS 39% / TDS 44% maximums and the 600 credit-score floor for insured files.

Illustrative in this file — lender-specific, not rules:
- ▸4.85% contract rate — rates move daily; not a quote.
- ▸a lender's own 'most recent NOA' policy — each lender sets its own documentation requirements; not every lender treats a not-yet-assessed year the same way.
