I hit a nasty pothole on the 401 the actually broke my left front wheel. The tire went flat instantly at 120 km/h. Had I not had both hand on the wheel at "9 & 3" I may have ended up off the road. The damage was not limited to wheel and tire. It also bent the lower control arm. That particular section of highway was under construction at the time.
Long story short, I contacted the MTO and was eventually compensated for the damage which was in the range of $1500.
