Ontario Highway Traffic Act

Sorry a 2-part question
I received a similar parking ticket as another member (Meghan) specified as Code 403 on the ticket and indicated as
Stop-Signed Highway During Rush Hour Period (4-6 pm) $150.00 (!)
I was parked on Broadview Avenue and went over by 50 min

I'm confused when looking at the Toronto Municipal Codes Chapter 950 updated Feb 20 ...
