I'm Cole Ginsberg, the owner of CFG Mechanical here in the GTA. I've been in the trades over ten years and I'm a fully certified plumber. I didn't plan on this path either, I started in construction doing landscaping and general contracting before plumbing found me and stuck. I sunk my teeth in low-rise residential, where you learn the most. You're in someone's home, things need to work right the first time. From there I moved into ICI work, running crews as a foreman on large commercial jobs, then spent a few years in high-rise construction handling mechanical systems most residential guys never touch. That's the background CFG Mechanical is built on. What sets me apart: I'm licensed and certified in both plumbing and mechanical — gas, boiler, hydronics, heating, venting, cooling. So you're not calling two companies and hoping they talk to each other. One call handles it. I cover 24/7 emergency service, HVAC, heating and cooling, gas work, indoor air quality, ductwork, thermostats, water heaters, plumbing, and hydronic heating including boilers and radiant systems — across residential, commercial, and multi-residential properties. Licensed. Certified. Built to be the one call that actually does it all.
