The client
A BC Interior silviculture and harvest contractor, paid by the cubic metre under contract to logging companies around Quesnel. A province-wide wildfire evacuation order closed the working forest for three of a normal seven-month season one year, cutting his operating window to four months. His spouse works part-time. He wanted to buy a home at 5% down, qualifying on two years of T1 self-employment income — standard practice for a sole proprietor without a longer, steadier income history.

The wildfire-shortened year, reconstructed by the month:
| Wildfire-shortened year | Figure |
|---|---|
| Net income actually earned | $27,000 |
| Operating months (evacuation order closed the rest) | 4 |
| Earning rate per operating month | $6,750 |
| Projected across a normal 7-month season | $47,250 |
The problem
A straight two-year average, using the wildfire year's actual $27,000 net against the following year's $51,000, produces just $3,250/mo — a number that reflects a province-wide closure order, not a slower business.
What the closure-truncated average actually showed
- ▸Straight average: ($27,000 + $51,000) ÷ 2 ÷ 12 = $3,250/mo
- ▸Combined with the spouse's income: $6,450/mo
- ▸GDS at that income: 41.7% — against CMHC's 39% maximum. Declined.
The business did not earn less per working month during the wildfire year — it simply could not operate for three of its usual seven months, by government evacuation order, not by client demand or a downturn in contracts. A T1 net figure that averages a closure into the same bucket as an ordinary slow season tells the underwriter nothing about what the business can actually sustain going forward.
The numbers
At 5% down on a $340,000 purchase this file sits at 95% LTV, the top insured band, so CMHC's 39%/44% caps govern outright.
| Structuring the insured loan | Amount |
|---|---|
| Purchase price | $340,000 |
| Down payment (5%) | −$17,000 |
| Base mortgage (95% LTV) | $323,000 |
| CMHC premium — 4.00% at 90.01–95% LTV, capitalized | +$12,920 |
| Total insured mortgage | $335,920 |
| Rate & payments | Figure |
|---|---|
| Contract rate — 5-year fixed (illustrative, not a quote) | 4.85% |
| Minimum qualifying rate — contract + 2% | 6.85% |
| Monthly P&I at the qualifying rate — the ratios run on this | $2,322 |
| Monthly P&I at the contract rate — what he actually pays | $1,925 |
GDS and TDS, raw versus normalized
| Ratio | Raw closure-year average (declined) | Normalized to a full season (approved) |
|---|---|---|
| Self-employed income used | $3,250/mo | $4,094/mo |
| Combined with spouse's $3,200/mo | $6,450/mo | $7,294/mo |
| GDS | 41.7% | 36.9% |
| TDS (GDS numerator + $300 other debt ÷ income) | 46.4% | 41.0% |
The same $2,322 qualifying payment sits behind both columns. What changes is whether the shortened year is averaged raw or normalized to what the business actually earned per operating month, projected across a normal season — the approach documented in rebuilding a file when the raw two-year average is unusable.
The solution
A BCFSA-licensed submortgage broker treated the wildfire year as a documentation problem, not a credit problem.
First, established the closure was external and dated. A copy of the provincial wildfire evacuation order, cross-referenced against the contractor's own harvest logs, confirmed the exact months the working forest was closed — a fact independent of the borrower's own performance.
Second, calculated the true earning rate. $27,000 over 4 actually-worked months is $6,750/mo of real earning capacity — not a business slowdown, a business that lost operating days it never controlled. Projected across a normal 7-month Quesnel season, that rate becomes $47,250, and the two-year blend with the following full season rises to $4,094/mo, in line with how a self-employed two-year average is meant to be built when a real, documented disruption interrupts one year.
Third, matched the file to a lender willing to normalize a documented, externally-caused closure rather than apply a policy built for ordinary seasonal variation.
The outcome & the closing math
Approved and funded insured at 95% LTV, 25-year amortization, 5-year fixed term. British Columbia's average new mortgage size is a useful benchmark against a $335,920 insured loan this size, and BC's Property Transfer Tax on the purchase was the remaining piece of closing cash to plan for:
| Cash due at closing (beyond the down payment) | Amount |
|---|---|
| BC Property Transfer Tax on $340,000 — 1% on the first $200,000, 2% on the remainder | $4,800 |
| Legal fees, title insurance & adjustments | varies |
The $17,000 down payment is exactly the 5% minimum this price requires — there was no room to structure around the income question, which is what made normalizing the wildfire year the whole file.
What to take from this file
- 01A closure order is not the same fact as a slow season. Confirm the disruption was external and dated before treating a low T1 year as representative.
- 02Normalize to a rate per operating month, not a rate per calendar month. Dividing a truncated year by 12 buries the real earning capacity inside the months the business could not work.
- 03The 95% LTV band leaves no down-payment cushion to structure around. When the minimum down payment is already in, the income calculation has to carry the whole file.
- 04Independent, dated documentation makes a normalization defensible. A government evacuation order and the contractor's own logs turned an assertion into a fact an underwriter could rely on.
