Turning right on a red light
It is generally permitted to turn right when facing a red light everywhere in Canada, EXCEPT on the Island of Montréal and at intersections where it is expressly prohibited by the sign on the right.

When you want to turn right on a red light, you must proceed with extra caution because you have a responsibility towards pedestrians. Before turning right on a red light, you must bring your vehicle to a complete stop!!! A complete stop is mandatory. Immobilize your vehicle before the stop line or before the pedestrian crossing zone. Pedestrians always have the right-of-way if their pedestrian crossing light allows them to cross. In the absence of a pedestrian crossing light, pedestrians have the right-of-way on a green light.

Turning right on a red light is not an obligation; it is a privilege. If you decide to turn, you must wait until the way is clear. Respect the decision of a driver who does not turn right on a red light; do not honk your horn to make him/her advance. Courtesy towards others on the road is always the order of the day!
 

Green light vs. flashing green
In Canada, there are 2 types of green light: the green light, and the flashing green. A green light means the same thing as in Europe. But when you are facing a flashing green light, it means that you have the right-of-way to make a left turn.

Required right turn, left turn, straight ahead,...
Pay attention to these road signs (right): they are important, especially for city driving. This sign indicates that you must turn right or continue straight ahead. You are not allowed to turn left under any circumstances.

There are signs like this for every situation: left turn or straight ahead, straight ahead through the intersection (i.e. you can neither turn left nor right), etc.

4-way stops
In a 4-way stop situation, the first to stop is the first to go. If two vehicles arrive at the same time, you yield to the vehicle on your right. It is a good idea to make visual contact with the other drivers to indicate your intentions.

Highway exit signs
Exit numbers are always indicated in a yellow box on highway exit signs (145 in the image on the right). Note that these numbers correspond to the distance in kilometres along the highway. So for example if your destination is Exit 155, when you reach Exit 145 you know that you have 10 more kilometres to drive before your exit.

Highway markers
In Canada and in the USA, highway markers indicate the highway number (20 East, 15 North,...) rather than the destination (direction Québec, Toronto,...).
