Founded in Toronto in 1979, Riva Plumbing Ltd. has grown into one of the leading plumbing contractors serving the Greater Toronto Area and surrounding regions. We support builders across a wide range of low-rise residential construction—from large-scale subdivisions to custom-built homes and estate properties.

Our team is built to help projects stay on schedule and on budget. Alongside skilled tradespeople in the field, we provide dedicated on-site foremen who work closely with site supervisors on scheduling, coordination, administration, and pre-delivery inspection (PDI) support.

Riva Plumbing’s tradespeople are proud members of United Association Local 46 and are trained and qualified under Ontario’s skilled trades system.  Our office team supports operations through estimating, contract administration, procurement, logistics, human resources, and project management—ensuring a consistent, accountable experience from tender to close-out.
