The neighbourhood

The firm's head office is at 117 Peter Street in downtown Toronto. Its second office isn't in a town centre at all: the address is on Lake Joseph Road, outside Parry Sound in Ontario's Muskoka region, a stretch of cottage country reached mainly by highway from the Greater Toronto Area. That geography lines up with the firm's practice list, which includes easements and title insurance disputes alongside its construction and engineering caseload, the kind of property disagreements that come up often around cottage lakefronts, where docks, boundary lines, and rights of way get contested.
