However you make your money, the law’s the same — and so are the deadlines.
The Construction Act doesn’t care which trade you run. Lien clocks, holdback windows, and WSIB filings hit every contractor the same way. TradesPilot does the date math for your job and watches it so a missed deadline never costs you the work.
How it works
Add the job once. We do the date math and keep watch.
Three steps. No spreadsheets, no calendar reminders you have to set yourself, no guessing which figure is the right one.
- 1
Add a job
Drop in the contract type and the dates that matter. We compute every lien, holdback, and WSIB deadline — preserve at +60 days, perfect at 150 total, including the Bill 60 holdback cascade.
- 2
We watch it
You don't have to remember any of it. Escalating push and SMS as a deadline gets close, so a date never slips while you're on a roof or under a panel.
- 3
Get paid
Bill HST right at 13%, send a Stripe payment link, and chase what is late automatically. Legal first, then paid — without the paperwork.
We’re watching it. That’s the whole promise — you run the trade, we hold the clock.
By trade
Find your trade. See the deadline that bites you.
Same law, different jobs. Here’s where each trade gets burned — and the typical invoice we keep CRA-compliant for you.
