The problem
Quebec's construction industry is governed by the Commission de la construction du Quebec (CCQ) under the Act respecting labour relations, vocational training and workforce management in the construction industry -- a placement system with its own hour-bank and seniority-based referral rules for unionized trades, producing genuinely irregular income in a tradesperson's first year or two regardless of how reliably they actually work. A first lender read the irregular T4 pattern as unstable gig-style income.
What the CCQ's system actually does
- ▸New certificat-holders are placed on jobs through the CCQ's own referral system, which prioritizes workers by accumulated seniority hours -- not by employer preference or the worker's own reliability
- ▸Placement gaps between jobs are a structural feature of the hour-bank system in a tradesperson's early years, not a sign of underperformance or unemployment risk
- ▸There is no equivalent registry or placement structure for a unionized trade anywhere else in Canada, so a lender's usual gig-economy heuristics do not actually describe this income pattern
The T4s looked like a pattern the lender had seen before, from workers who really were unreliable. This one was not that pattern -- it was the CCQ's own system working as designed, a distinction most guidance built for new-to-Canada underwriting does not cover.
The numbers
Once the CCQ's own hour-bank record was supplied, averaging the income appropriately was routine underwriting.
| The insured purchase, on CCQ-averaged household income | Amount |
|---|---|
| Base mortgage (90% of purchase price) | $268,200 |
| CMHC premium (3.10% at 90% LTV) | +$8,314 |
| Total insured mortgage | $276,514 |
| Ratio check at the qualifying rate | Figure |
|---|---|
| Payment at the qualifying rate (7.05%), 25 years | $1,945/mo |
| GDS (payment + $225 tax + $100 heat) ÷ $6,100 income | 37.2% |
| TDS (GDS numerator + $180 car loan) ÷ $6,100 income | 40.2% |
37.2% and 40.2% sit comfortably inside CMHC's 39% GDS and 44% TDS maximums once household income was correctly averaged against the CCQ's own placement record -- a documentation step that mattered more here than any add-back or offset methodology, since the underlying income was real T4 income the whole time.
The solution
A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services treated the CCQ's placement system as its own documented income pattern, not a generic self-employment or gig-income problem.
First, obtained the CCQ's own attestation of hours worked and placement history directly from the commission, rather than relying on the T4s alone to explain the gaps.
Second, explained the hour-bank and seniority-referral system's structural effect on a first-year tradesperson's income pattern to the lender, distinguishing it clearly from unstable or discretionary gig work.
Third, moved the file to a lender that would average the documented household income against the CCQ's own record rather than declining on the T4 pattern alone.
The outcome
The purchase funded insured at 37.2% GDS and 40.2% TDS; Quebec's welcome tax on the $298,000 purchase came to $2,666.
Both ratios sit comfortably inside CMHC's 39% GDS and 44% TDS maximums.
What to take from this file
- 01Quebec's unionized construction sector runs on the CCQ's own hour-bank and seniority-referral placement system -- a structure unlike anything else in Canada. Recognize it by name before reading its income pattern as generic instability.
- 02A CCQ attestation of hours worked documents the placement pattern directly from the regulator. It is a stronger, more specific document than the T4s alone for explaining an irregular pattern.
- 03Placement gaps in a first-year unionized tradesperson's schedule are structural, not a reliability signal. Distinguish this from gig-economy income before a lender applies the wrong heuristic.
- 04Household income from two sources, correctly documented, can carry a file even when one income's pattern looks unusual on paper. Document each source on its own terms.
Sources
Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.
- ▸CMHC — Purchase (Mortgage Loan Insurance) — default-insurance premium schedule by LTV band (25-year amortization).
- ▸CMHC — CMHC Home Start — minimum down payment tiers (5%/10%) and the $1.5M insured price cap.
- ▸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.
- ▸Provincial/territorial mortgage-broker legislation fetched directly (bclaws.gov.bc.ca, legisquebec.gouv.qc.ca, fcaa.gov.sk.ca, web2.gov.mb.ca, nslegislature.ca, assembly.nl.ca) plus FCNB's own site for NB and CanLII's index for PE — see notes for per-province method — provincial mortgage regulators and licence titles.
- ▸Gouvernement du Québec — Droits sur les mutations immobilières — Quebec's transfer duties ('welcome tax') — 2026 indexed brackets.
Illustrative in this file — lender-specific, not rules:
- ▸5.05% contract rate — rates move daily; not a quote.
- ▸the CCQ's own hour-bank averaging approach — each lender sets its own policy for averaging a unionized construction income pattern; this is not a universal CCQ or CMHC rule.
