Heather Stilwell (January 26, 1944 – December 3, 2010) was a Canadian political activist and former school trustee in Surrey, British Columbia. A staunch Roman Catholic, she was well known for her opinions opposing homosexuality, abortion, and sex education.
She and her husband Bill were involved in the creation of the Christian Heritage Party in 1984 after a dozen or so people discussed the concept of such a party, which was registered with Elections Canada in June 1986.
From April 1993 to March 1994 she was the interim leader of the party and ran in the 1993 federal election in the riding of Surrey—White Rock—South Langley. One of the most contentious policies of the Christian Heritage Party Policy is Section 6.4.3. which states: "Concerning the welfare of this Nation's citizens, we favour recriminalizing in the Criminal Code of Canada the murder of pre-born children, sexual deviancy, and pornography." She entered the leadership race for the CHP at the 1994 convention, but withdrew and instead ran for the party presidency.
Heather Stilwell was also executive vice-president and leader of the socially conservative Family Coalition Party of British Columbia which later merged into the British Columbia Unity Party. Stilwell ran unsuccessfully in the 2001 provincial election, as a candidate in the riding of Surrey-Panorama Ridge.
