The charge looks like it was for driving in an HOV lane and from my admittedly hasty research I think the OP may have a case. The regulations for S. 154.1 only list HOV designations on a number of 400 series highways. However Toronto By-law 950-503 seems to regulate HOV lanes on city streets in Toronto. It looks to me like the officer may have charged the OP under the wrong law. I've posted what seem to me to be the relevant pieces of legislation here. What do you all think?
