How it is made

For each city we ran Google Maps searches for agency types, then read each agency's own website for contact details. Duplicates are removed by website and phone. Agencies can ask to be removed (email us with the subject "Remove"), honoured in every later file.

Buyer's duty: in Canada, CASL is stricter than CAN-SPAM; check its conspicuous-publication rules for business addresses before sending. Identify yourself and include an opt-out in anything you send.
