Marc is one of Ontario's foremost legal authorities on co-ownership conversions, having developed and instituted much of what is now the official process.

Mr. Lean has one of the largest condominium conversion practices in the Province. Current projects include the conversion of over 500 units in the City of Hamilton for national REITs in Toronto and Victoria; the conversion of 220 units in the City of Mississauga for a private developer and a private equity REIT; the conversion of 32 townhouses in the City of Oshawa for a private developer; and the conversion of over 300 units in the City of Kitchener for a Toronto-based REIT - the largest conversion in a single project ever developed in that city.
