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.
