Pierre Sirois · Founder
Built in Ottawa, since 1989.
An Ottawa native and Concordia graduate, Pierre founded Sirois & Sons in 1989. The firm grew from landscaping and basement renovations into one of the city's most trusted general contractors. "I'm in this business because I love helping homeowners complete their dream projects with the support of my team and our trusted trades."
He credits the firm's success to a team that stays — many tradespeople have been with Sirois & Sons for twenty to twenty-five years.
