Mark Oldershaw, born February 7, 1983, in Burlington, Ontario, Canada, is a Canadian sprint canoer.
Oldershaw was a double gold-medalist at the Junior World Championships in 2001, winning both the C-1 500 m and C-1 1000 m events.
Oldershaw competed at the 2008 Summer Olympics in Beijing but was eliminated in the semifinals of the C-1 500 m event. Three years later, he participated in the 2011 world championships in Szeged, Hungary where he came 5th in the C-1 1000 meter event.
Oldershaw is relishing the chance to avenge his Olympics defeat when he competes again as part of Canada’s team for the 2012 Summer Olympics.
