For a decade we've helped GTA families and investors buy, sell, and grow their portfolios, with bilingual, data-led service that's personally handled from the first call to closing day.
Before real estate, Maz spent over a decade in cancer genomics research at UHN, Sinai Health, and the University of Toronto. That work was built entirely on reading data carefully and getting the details right. He brought that same discipline into real estate, and built CIEL to serve GTA families, investors, and francophone and newcomer clients with the same rigour.
Today he leads CIEL Homes & Condos alongside partner Monika Kostrzewa, with hundreds of transactions closed across Oakville, Mississauga, Toronto, and the wider GTA.

Working with Maz Riverin and the CIEL Homes & Condos team was an outstanding experience from start to finish. Maz and his team were honest, hard-working, professional, and incredibly knowledgeable about the real estate markets in both Toronto and Oakville. They understood the differences between property types and guided us through both sides of our move: selling our condo in Toronto and buying our home in Oakville. The condo market was not easy at the time, but Maz marketed our property exactly the right way and helped us achieve top dollar in a downturn. On the purchase side, he moved quickly, strategically, and confidently. Everything came together in less than two weeks, with no surprises and no headaches. We felt supported, informed, and protected throughout the entire process. We highly recommend Maz Riverin and the CIEL team.
Maz Riverin and the CIEL Homes & Condos team helped us purchase our home during one of the most competitive periods in the market. Even though there were many competing offers, Maz helped us secure the home without overpaying. He was strategic, calm, and very clear about the risks and the process. One of the best decisions he guided us toward was obtaining a home inspection before going firm, so we could move forward with confidence and understand the condition of the property. We have now been living in our beautiful Milton home for the last five years, and we have no regrets. Maz and his team were professional, knowledgeable, and truly looked out for our best interests.
