Markham—Unionville
Riding Overview
Traditionally a safe non-Conservative riding, Markham—Unionville has been somewhat rearranged. In 2011, the Conservatives came within 4% of taking the seat from the Liberals. According to 2011 results in the newly defined area, the Conservatives would have won the seat with 46% of the vote. The current MP, Liberal John McCallum, has held the seat since 2004, but he is running in a different riding in October.
