Do I need a new Work Permit or change in conditions will work

[mkuma23]

Hello Experts

I got the work permit last year which is valid till 2010 through a company A. But due to unavoidable circumstances I could not go to canada. I never entered canada on my work permit.

I want to know in case if I get a job now in Canada for Company B. Do I will need to reapply for new visa or only change in conditions of work permit will work? How do I get my new employer name changes in my file?

I guess new visa will not be required untill 2010.Please provide your inputs.
