Ontario Stone Design Center scores 40 of 45 on what its customers said, 0 of 25 on what it states about itself, and 30 of 30 on its website and record. Nothing here has been checked with a registry, an insurer or the WSIB.

The review pillar uses public Google review data republished here, and the ratings are set by reviewers, not by Countertop Installers.
