Why are some of these painters based elsewhere?
St. Catharines is the listed address for 10 of the 15 companies on this page; the rest are based in other towns or show a service area instead of an address. Painting crews travel to the work, so an address in the next municipality matters much less here than it would for a walk-in business.
