On the following link on CIC web site http://www.cic.gc.ca/english/work/worker-3.html in the section "Applying for a Work Permit from Inside Canada" it says that "You may apply for a work permit after coming to Canada if: You have a temporary resident permit (TRP) that is valid for six or more months."
What I want to know is that a Visitor Visa is also an TRP so why a Visitor has to apply outside of Canada when a Visitor have a valid TRP.
Please reply.
