David Mercier

David Maurice Mercier (July 20, 1939 – April 12, 2021) was a Canadian politician.

He served in the Legislative Assembly of British Columbia from 1986 to 1991, as a Social Credit member for the constituency of Burnaby-Edmonds.

On October 3, 1989, Mercier and three colleagues — Graham Bruce, Duane Delton Crandall, and Doug Mowat — quit the governing Social Credit caucus to sit as "Independent Social Credit" members.

In a joint statement, the four stressed that they "in no way desire[d] the fall of our government", but wished to spur an "open and realistic assessment" of Bill Vander Zalm's continued leadership.

Mercier explained his move by saying his concerns about Vander Zalm's leadership and re-election chances had been addressed.
