About Diamond Fischman & Pushman

Diamond Fischman & Pushman is a small law firm in downtown Oshawa that has served Durham Region since 1969. The firm concentrates mainly on residential real estate, handling purchases, sales, and mortgage or refinance closings, and it's part of Ontario's electronic land registration system, so it can complete real estate transactions anywhere in the province. Beyond real estate, it also takes on commercial transactions, wills and powers of attorney, family law matters such as separation and custody, and corporate work for small and medium sized businesses, including incorporations and shareholder agreements.

Clients meet directly with a lawyer on their file rather than being routed through a larger team, and the firm arranges after hours and weekend appointments when needed. In some circumstances it will attend a hospital or a home so a client can execute documents in person. The office is on King Street East in downtown Oshawa, with appointments available in Toronto as well.

The neighbourhood

The firm's office sits on King Street East in downtown Oshawa, a city long associated with General Motors of Canada, which built its Canadian headquarters there and, in 2021, reopened an assembly plant to build pickup trucks. Oshawa anchors the eastern edge of the Greater Toronto Area and Durham Region, and its downtown core has been designated an Urban Growth Centre as the city adds residents and post secondary students. That kind of growth keeps residential real estate moving through Durham Region, which fits a firm whose main work is helping people buy and sell homes there.
