WSIB for Ontario contractors

A clearance certificate is what a general contractor checks before they release your money, and it expires on a date nobody puts in a calendar. These guides cover registering, what the premium adds to every billable hour, the clearances you have to collect from your own subs, and the renewals that lapse in the middle of a job.

Try this on a real business

Open a seeded business in your trade. Nine jobs on the pipeline, a quote sent and viewed, a deposit paid, an invoice overdue, and a holdback on the current month.
