Can't be of much help without the code. Check with your local DIY parts stores and see if they offer loan/use of a OBD II code reader. I purchased my own reader for $99. It has paid for itself many times over. Otherwise consider getting an estimate for repair from the local mechanic. In the USA, Federal regulation requires 2yr 24,000 mile warranty of most emissions and 8 year 80,000 mile warranty on specific parts, so check with your dealer as they may fix it for free if Canada has similar protections.
