I have not had any problems in our travels going through toll booths. A very tight one was entering the U.S. at Sarnia/Port Huron. I had to maneuver my mirror around a stanchion, and when I exited the booth My mirrors were about 1" from the farther side booth. Tight, but doable.

It is what it is, and then it is what you make of it.
