A SIN number is your ID number with the Canada government.  It is used for your taxes.  When you come to Canada on a work permit or as a PR, you need to apply for a SIN card so you can give the number to your employer.  Without it, they can't pay you.

As far as I know, there is no difference between work visa and work permit.
