I hold a TWP, and TRV. I was offered a secound job, a lawyer in BC told me that if an other employer gets a secound LMO for me he can get a secound WP, as far as I know this is not possible I am right?, would be a legal move?
As far as I know, if you get a new LMO and a new work permit, it will invalidate your old work permit.
I have heard of some people believing that they can still work for the old employer as well as the new one but I think that's wrong and they would be working illegally for the old employer after they get the new work permit.
However, call CIC and ask. They will tell you. The lawyer could be out to make money and probably doesn't care if you work illegally and get caught and deported.
