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: 


Is this number negotiable at all? 
Is it rude to ask for extra money to cover relocation expenses (US to Canada)? 
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?
In my experience, postdocs are grant-funded with a nonnegotiable salary. It doesn't hurt to clarify though.
The department chairs I have known would not have considered this rude. Reimbursement for moving costs is often offered as a sort of signing bonus. 
Reimbursement for parking is unheard of in my experience. Again, asking politely shouldn't be a problem, but I wouldn't get my hopes up.
