Plumbers
From One Van to Ontario's Best
Thirty years of showing up, doing the job right, and earning Ontario's trust. One pipe at a time.
The Beginning
Gord Kowalski started Maple Leaf Plumbers with one van, a set of tools, and a promise to treat every customer like a neighbour. His first job? A leaky faucet right here in Cambridge.
Going Commercial
Our reputation for reliability landed our first commercial contract, servicing a network of downtown condos. The fleet grew to four vehicles.
A Growing Team
With 10 licensed plumbers on staff, Maple Leaf expanded into full bathroom renovations and new construction across Ontario.
Award-Winning Service
Maple Leaf Plumbers was named Ontario's Best Plumber by HomeStars for the first time, a recognition we've proudly earned every year since.
24/7 Emergency Line
We launched our round-the-clock emergency service. No more waiting until morning for a burst pipe. We're here whenever you need us.
8,000 Customers
Despite a challenging year for everyone, we hit a major milestone — 8,000 satisfied customers across Ontario. We gave the lucky customer the whole job free.
9,628+ and Counting
A team of 21 licensed technicians serving communities across Ontario, with the same values Gord brought to that first job in Cambridge back in '96.
