Sir Robert Borden introduces the first income tax in Canada as a "temporary" measure (lowest bracket is 4% and highest is 25%).

Sir Robert Laird Borden was the eighth prime minister of Canada, serving from 1911 to 1920. He is best known for his leadership of Canada during World War I.

Income taxes constitute the majority of the annual revenues of the Government of Canada, and of the governments of the Provinces of Canada. In the fiscal year ending March 31, 2018, the federal government collected just over three times more revenue from personal income taxes than it did from corporate income taxes.
