I have a question! I have been driving in Ottawa these days and I want to ask whether cars are allowed to turn right at a red light at intersections and T-intersections ?

When it's prohibited to turn right, there will be signs indicating a red light, which can be understood. If there are no signs, you can go.

It depends. Generally speaking, you can turn right on red at most places except Quebec. But there are some special places with signs to tell you that you can only turn right after the turn signal turns green. Anyway, stop at a red light and look up at the sign carefully to make a decision.

In general, you can turn right, but you must stop for 1-3 seconds, observe that it does not affect the left vehicle, and then continue driving.
