Who handles what
The neighbourhood
Ivanov Katz LLP's office is at 3 Church Street, Suite 500, in Toronto's St. Lawrence Market area. The building was built in 1914 and completely restored in 1985, and it's designated under the Ontario Heritage Act as part of the St. Lawrence Neighbourhood Heritage Conservation District, with the red brick, stone detailing, and Edwardian Classical lines typical of the district. Its old commercial tenants included H.S. Howland Sons & Co., a wholesale hardware business, in the 1920s through the 1940s.
The surrounding blocks mix restaurants, shops, and residential buildings around St. Lawrence Market, and Union Station and the King subway station are each about a five minute walk away, which makes the office an easy stop for clients coming from elsewhere in the city or from out of town.
