About Cargill Kert Professional Corporation

Cargill Kert Professional Corporation is a small law firm based in Markham, Ontario, with a second office in Mississauga. It has served the Greater Toronto community for more than 15 years, building relationships with lending institutions, real estate agents, brokers, and the city that it uses to keep purchases, sales, and refinances moving efficiently.

The firm is made up of two lawyers, Constance Cargill and Miran Kert, both holding a B.A. and an LL.B. Cargill Kert practices in three main areas: real estate (residential, commercial, and agricultural transactions, leases, mortgage financing, and title insurance), business law (incorporation, franchising, shareholder and partnership agreements, and commercial contracts), and wills and estates, ranging from routine estate planning to will challenges, executor disputes, and guardianship matters. Both offices also provide notary and commissioner of oaths services, including certified copies, statutory declarations, and letters for travel or marriage abroad.

The neighbourhood

The firm's main office sits on Woodbine Avenue in Markham, a York Region city that has grown into one of the Greater Toronto Area's technology and corporate hubs, home to the Canadian or North American head offices of companies like Honda Canada, Toyota Financial Services, and IBM. That kind of corporate and residential growth generates a steady stream of real estate and business work, the two areas Cargill Kert concentrates on alongside wills and estates.

The Mississauga office, on Dundas Street East, puts the firm in Ontario's third largest city, part of Peel Region and another corporate centre where dozens of Fortune 500 companies keep Canadian or global head offices. For clients on the west side of the GTA, it means a local office rather than a trip out to Markham for a real estate closing or a wills appointment.
