I like 5W30, it is readily available everywhere and costs less too.

For Canadian winters, I would use 0W30 full synthetic. "0W" is the important part for you, where "0" stands for viscosity grade when the engine is cold and "W" stands for Winter. "0" weight has lower viscosity than "5" weight, so with "0" weight you will have an easier time starting the engine during the winter. "30" is the viscosity grade at normal engine operating temperature. Per my previous comments, your 1.8L engine will be much happier and last a lot longer with 5W30 (during summer) and 0W30 (winter or all year round), preferably full synthetic in either case.
