Stunt driving in Ontario is serious: 30-day suspension and 14-day impound right away, then conviction means at least $2000 fine, 6 demerit points, and 1+ year suspension, plus huge insurance hikes.
Many fight it by challenging speed evidence or procedures. Check Traffic Paralegal Services https://www.trafficparalegalservices.com/stunt-driving/ for details on penalties and defences. In principle, experienced paralegals can often get charges lowered to something less severe.
