Where these numbers come from

For Longueuil, Metal Shop Guide covers Longueuil and the South Shore and lists 108 shops. All of them have a website of their own, and we read them, as of October 28, 2026. “Not shown” means we didn't find it on the pages we read. A blind check of 40 shops suggests each share is a few points high.

One shop is 0.9% of the Longueuil total, so small gaps can be chance.
