Ontario Provincial Police are out with a warning ahead of the long weekend and it targets a couple of specific types of vehicles.
They say this is the time of year when owners of motorcycles and off-road vehicles take them out of mothballs and hit the roads and trails.
The warning from the OPP is for all motorists to be aware of their surroundings, since close to half of all motorcyclist deaths last year were not the fault of the bikers.
OPP say 48 motorcyclists lost their lives on provincial roads last year, which was over a 10 year high.
Several factors were at play in the deaths including impairment, improper turns, excessive speed and failing to yield.
As for off-road vehicles, 22 drivers were killed and police say 9 of those killed were not wearing helmets.
