The neighbourhood
The firm's head office sits on Kingston Road West in Ajax, a growing community in Durham Region just minutes east of Toronto along Highway 401. Durham's regional economic development office describes Ajax as home to a diverse, growing population with easy access to Highway 401, 407, and 412. That growth lines up with the firm's real estate practice, which it describes as one of the largest by volume in Durham Region, handling a steady flow of residential purchases and sales in and around the town.
The firm's other two offices, in North York and in Mississauga, operate by appointment only, so most of the day to day work happens out of the Ajax location.
