The father and son from Montreal had last been seen on March 9, when they rented a toboggan from the Chateau Lake Louise hotel.
They were only reported missing five days later on March 14, after failing to check out of their hotel room.
The RCMP requested the help of Parks Canada search and rescue personnel to help look for the two over the weekend.
A Parks Canada dog handler found the victims buried under debris at the base of Mount Fairview on the shore of Lake Louise.
