All of them: construction projects in Toronto by address. Builtie's Toronto data is the amalgamated City of Toronto, including Etobicoke, North York, Scarborough, East York and York. Mississauga, Brampton, Vaughan, Oakville and Burlington issue their own permits; Builtie has read them separately since October 2026, so a Toronto count is not a GTA count. Toronto states a construction cost on about a third of 2026 permits.
Plans
Builtie's Starter plan is $79 per seat per month for 20 projects; Growth is $99 for 50 projects and adds the LinkedIn and email outreach you run yourself. Opening a project spends one credit, and the decision makers, emails, phones and AI call script inside it are included.
