Trade Playbook
General contracting is not a certified trade in Ontario — there is no provincial "general contractor licence." What gates the work instead is municipal business licensing, building permits, and (for new homes) provincial home-builder licensing.

Ontario does not issue a province-wide general contractor licence. Your obligations are mostly municipal: most municipalities require a business licence to operate, and every project needs a building permit pulled by an owner or authorized agent. If you build or substantially renovate new homes you also fall under HCRA licensing (see New Home Building). You self-perform or subcontract compulsory trades (electrical, plumbing, HVAC) only through certified people or licensed contractors.
GCs carry the broadest exposure because you are responsible for the whole site. Most owners and GCs require $5M Commercial General Liability (CGL), and you should confirm every subcontractor carries their own CGL and WSIB clearance before they set foot on site.
