Oh.. only 17 flight hours. It's quite too few for 6 months training duration. How often have you flied per week?
I got some information from Harv's Air located in Manitoba. They told me that there would be at least 300 days a year having clear weather. You can check it out whether the weather in Manitoba might be better or not.
Sorry that I cannot give you more support. I am just curious because I am now interested in taking course in Canada and trying to search more info about weather there as well.
