Guthrie Muscovitch Architects is a Toronto-based design firm founded in 1988 by partners Randy Guthrie and Arthur Muscovitch. Since its inception, GMA has been at the forefront of residential design in Ontario. We have worked on sites as small as a single family lot, as broad as city precincts, and as diverse as large-scale condominiums, seniors’ housing, resorts and new subdivisions. Our experience and track record have benefitted our clients in realizing over 10,000 units of housing. GMA is
