​​Don Adamson Plumbing and Heating Limited


Don Adamson Plumbing and Heating Limited is a second generation, owner operated business established in 1957. My father built our strong business reputation by providing superior quality plumbing services that consistently exceed customers’ expectations. Although we service many commercial accounts, our origin is in residential plumbing.

Following in my father’s footsteps, I attended George Brown College completing the Plumber Apprenticeship Program in 1979, achieving the highest grades in my class. After having obtained an Interprovincial Journeyman Plumbing License I continued my training and in 1981 became the youngest Master Plumber in the city of Toronto.

In 1984, my father retired and I became president and owner of the company.  Today, after 33 years of leadership, I’m proud to uphold the same high standard of integrity and professional conduct.
