Hello. I couldn’t ignore your question because I myself found myself in a similar situation. I don’t know how to search and find specialists at all. Especially when the issue concerns repairs. And in general, I’m not a very experienced Internet user, and I don’t have many acquaintances in Toronto yet. But miraculously I found the company POM Plumbing Inc https://pomplumbing.ca/commercial-plumbing/ and we agreed to cooperate with them. They have already completed the first stage of work and I am very pleased. So I can confidently recommend them to you.
