John Rosolak was born in 1959. His professional life developed in Toronto, the capital of Ontario and the province's largest city, where he trained in law and later practiced.
In Ontario, lawyers were admitted to practice by the Law Society of Upper Canada, the provincial licensing body that later became the Law Society of Ontario. Rosolak's admission in 1985 placed him within this regulated profession at the start of his career.
Rosolak studied at the University of Toronto, where he received a Bachelor of Laws in 1983. Founded in 1827 as King's College, the University of Toronto grew into one of Canada's largest universities and a major centre of legal education in Ontario.
The Bachelor of Laws was the principal professional law degree in Canada at that time. Rosolak was admitted to the Ontario bar in 1985, two years after completing the degree.
Rosolak's documented career is associated mainly with Weir & Foulds, a Toronto law firm. WeirFoulds LLP is described as one of Canada's oldest law firms, and its origins trace to a practice opened in Toronto in 1860. The firm's work covers litigation, corporate, property, and government law.
He was admitted to the Ontario bar in 1985 and practiced at the firm as a partner. Professional profiles associate his practice with civil litigation, environmental and municipal law, and employment and labour law, while another directory lists aviation law and bills of exchange among his areas.
A Lexpert report on a $100 million claim by BCE noteholders named him, together with two Weir & Foulds colleagues, as counsel acting for the noteholders in the proceedings.
