FinTech thesis · Canadian construction payments

Canada put a legal clock on construction payments. Trade contractors still can't see it.

Proper would tell an electrical or mechanical contractor when each invoice is legally due, which one protects the next payroll, and what to do when it's late. Later, it could pay them early on invoices the law has already made payable.

The problem

In Ontario, an owner has 28 days to pay a proper invoice, and each tier below has 7 days to pass the money on. Since January 2026, an invoice counts as proper unless the owner disputes it within 7 days. Most trade contractors still run cash from an aging report and a credit line.

The clock

Check one draw against your payroll

Enter the day the owner received the GC's invoice that includes your work. The bar shows the latest date the law allows at each tier, and where your payroll falls.

Simplified Ontario prompt-payment rules for illustration. Disputes, notices of non-payment and contract terms can change the dates. This is not legal advice.

Market size · my scenario model, not a published forecast

The Canadian market is small. It gets large only with U.S. expansion and early-pay revenue.

Buyers are specialty trade contractors with 10 to 99 staff: 18,436 locations in Canada (June 2026) and 88,062 U.S. firms (2022). The pool is buyers × fit × paid adoption × price, plus early-payment fees. Fit, adoption, price and take rate are my assumptions, which is why the range is wide.

In the base case Canada is about C$6M today. Reaching C$1M ARR would take 278 Ontario customers, about 11% of the contractors who fit.

First four weeks

Nothing here is validated yet

I have not spoken to a customer about this. The first test costs close to nothing:

  • 20 interviews with owners or controllers of Ontario commercial trades, found through trade associations and construction bookkeepers.
  • A C$500 concierge audit for five firms. I would compute the legal date of every invoice from six months of receivables, by hand.
  • Go if at least 8 of 20 had a late invoice force a costly move, at least 3 pay or sign a C$300/month letter of intent, and the audits find 15% or more of receivable value past its legal date.
What would make me stop
  • Trades say they won't use their statutory rights at any price because they fear losing the GC. I would then test selling compliance to GCs, or stop.
  • GC portals already show legal due dates for most invoices by value.
  • Setting up a customer's data takes more than an hour, which breaks the economics.
  • No lender will price early pay below about 2%. Proper would stay a smaller software business.
