A pileup on the E.C. Row Expressway caused major headaches during the Wednesday morning commute.
The westbound lanes between Dougall Avenue and Dominion Boulevard were closed for a short period after two separate crashes.
Windsor police tell CTV News, traffic began piling up on the Dominion off-ramp.
The long line caused two separate crashes one involving two vehicles and then another involving five.
Several people have been taken to hospital.
The off-ramp re-opened just before 10 a.m.
