If you get your Canadian Permanent Residency, you are treated at par with Citizens and other Permanent Residents with respect to employment and most other rights. This policy/law/rule is as in the US.
Funds must only be in the name of the principal applicant.
Good sites to do research are:

I am living in the US and thinking of moving to Toronto. I am thinking of getting the Permanent Residency card but not settling immediately. Since only have to show two years out of five, I will delay my move until I get the best job offer of both countries. Meanwhile I intend to make short jaunts to Canada for a week per two months and share an apartment/basement with someone (students?) while searching for jobs. I think this is optimal if I want to reduce money burn rate.
