David Mainse (August 13, 1936 – September 25, 2017) was a Canadian televangelist, broadcast executive and producer, and an evangelical Christian leader.
He took the initiative and obtained a $100,000 a year, 20-year lease on a building at 100 Huntley Street in downtown Toronto that was suitable for conversion into a television studio.
In 1979, outside the Toronto mayor's office, Mainse protested the gay publication The Body Politic, saying that "parents and all decent people are particularly disgusted by the perversity, which publishes and disseminates anti-child, anti-parent dehumanizing materials."
[3] In 2009, Mainse returned to host 100 Huntley Street while his sons Ron and Reynold stepped down from the ministry while under investigation concerning an alleged Ponzi scheme.
[5] In June 2012, the same month as Crossroads' 50th anniversary, Mainse was presented the Queen Elizabeth II Diamond Jubilee Medal at a gala event at Roy Thomson Hall.
