Definitions
Abortion (induced). The Therapeutic Abortion Survey collects data on legally induced abortions. The survey excludes illegal abortions and spontaneous abortions (that is, miscarriages).
Induced abortion is defined as the medical termination of pregnancy. Equivalent terms include: artificial abortion, therapeutic abortion, voluntary termination of pregnancy, elective termination of pregnancy, and active termination of pregnancy.
The term 'therapeutic' remains in the title of the survey for the sake of historical consistency. From late 1969 (when the survey first began) until 1988, a woman could only obtain an induced abortion if a committee of at least three physicians determined that the pregnancy was a risk to the woman's life or health (including mental health). In January 1988, the Supreme Court of Canada struck down the 1969 abortion law, thus removing the requirement of a health or therapeutic reason to obtain an abortion.
Age. Age (in completed years) of the woman undergoing an abortion procedure, on the date the pregnancy was terminated.
Area of report. Area of report refers to the province or territory in which the abortion was performed. Prior to 2004, reports of abortions performed on Canadian residents in the United States are also included where applicable.
Area of residence. Area of residence refers to the usual province or territory of residence of the woman obtaining the abortion. Statistics on non-residents of Canada who obtained an abortion in Canada are also included where applicable.
Type of facility. The Therapeutic Abortion Survey collects information on abortions performed in two types of facilities: hospitals and clinics.
