While no precise figures exist, it is estimated that approximately 4,000 to 6,000 Canadian women died from illegal abortions between 1926 and 1947. This lesson was reinforced in 1990 by the Conservative attempt to recriminalize abortion. A Conservative federal government, led by Progressive Conservative Prime Minister Brian Mulroney, introduced Bill C-43, which would punish doctors with prison terms if they performed abortions for women whose health was not at risk. It passed the House of Commons by a close vote of 140–131 in a blaze of publicity. It was not yet law, but within a week a 20-year-old university student bled to death in residence from a self-induced coat hanger abortion. A teenaged girl was injured in a botched back-alley abortion. These casualties of unwanted pregnancy received considerable publicity and abortion rights demonstrations were held after the death of the student, protesting Bill C-43. The bill was defeated in the Senate by a tie vote in early 1991 and the casualties of illegal abortion ceased.
