Is the postdoc salary negotiable in Canada?

I'm a statistician being offered 45k CAD for a postdoctoral position in Canada. I have a few questions:

1. Is this number negotiable at all?


2. Is it rude to ask for extra money to cover relocation expenses (US to Canada)?


3. The cost of a parking pass is 1000 CAD per year at this place (compared to 200 per year for faculty at my current university). Is it weird to ask for this to be compensated?
