I only know Ontario, so "HTA Part VI" - you only need 2 forward white lamps, and 1 rear facing red lamp. 2 rear lamps are standard on cars since we have corners and indicators which must be visible from the side. The third, red, rear lamp can be disconnected if desired, and 1 of the 2 rear brake lights can burn out and you're still in the clear.

So long as they are red but not flashing, it's perfectly fine.
