Britton Bath Osler
From Wikipedia, the free encyclopedia
Britton Bath Osler (19 June 1839 – 5 February 1901) was a Canadian lawyer and prosecutor.
The older of three famous brothers (the other two being Edmund Boyd Osler and Sir William Osler), he was born in Bond Head, Canada West.
He first rose to national prominence by helping to secure the conviction of Louis Riel on charges of treason following the North-West Rebellion of 1885. He subsequently represented the government of Canada in arbitrations with the Canadian Pacific Railway arising from construction contracts carried out by contractor Andrew Onderdonk. He is also noted for his role as a prosecutor in numerous lurid murder trials, including that of Reginald Birchall.
B.B. Osler is also known for founding the law firm McCarthy, Osler, Hoskin & Creelman (later known as McCarthy, Osler, Hoskin & Harcourt) with D'Alton McCarthy, the predecessor to today's firm Osler, Hoskin & Harcourt. Approximately 15 years after D'Alton McCarthy's death, his son and two nephews split from McCarthy, Osler, Hoskin & Harcourt to begin their own firm, the predecessor to the firm known today as McCarthy Tétrault.
