About Groundwire

Groundwire turns Canada's fragmented, technically-public building and development permit records into a single searchable, alertable dataset — starting with Metro Vancouver, expanding to Ontario and Alberta metros.

Every fact on this site links to the authoritative municipal source record it was read from. We publish what the municipality publishes — nothing enriched, nothing editorial.

Found an error? Every record's source link lets you verify against the municipality directly; a report-an-error channel is coming with the first live data.

Radius and keyword alerts — get notified when a new permit is filed near an address, or matching a trade or keyword — are an upcoming paid feature, not yet available.

Today, each municipality page that isn't yet live has an email waitlist you can join to hear when coverage goes live for that area. Pick your municipality on the coverage page to join its waitlist.
