I am a US citizen moving to Canada with my wife and son in July. I have received my provincial nomination in BC and am at the work permit application stage. I will be applying for a t13 LMIA exemption. Our moving company requires a work permit in order to pick up our belongings. My question is: are we able to apply for our permit at the border in advance of our final move? Our plan would be to go to the border at either the bridge or the tunnel in Detroit. We would then drive back to Wisconsin, where the movers would pick up our belongings before driving to BC. The alternative would be moving first and having our belongings picked up later. Any information would be appreciated.
