Statistics Canada says nearly one in five people aged 65 and older reported working at some point during 2015.
That's almost double the number reported in 1995.
Stats Canada says that could be due to a number of economic and social factors.
It says some may work past the traditional retirement age by choice, or out of necessity.
It suggests the higher employment rates could also be related to an increase in the debt levels of older Canadians.
