A compulsory trade is one where the work itself is restricted: you hold the certificate, or you are a registered apprentice working under someone who does, or you are not allowed to do it. A voluntary trade has no such restriction, and the certificate is still the thing a general contractor asks for before they let you on the site and the thing an insurer looks at when they price your policy.
Once the certificate is yours, the next wall is incorporation, WSIB clearance, insurance certificates and getting paid on time. AEC Stack handles all of it.
