For one of my jobs, the parent company is registered in Alberta but the workplace/restaurant is in Saskatchewan. The LMO will only show the address of your workplace. Any LMO or provincial nomination applications will have to be sent to the office for the province where the work is done by foreign workers.
Its like talking to a rock. It doesn't matter where the office is, they apply to the office where they are located (BC) and the location of work is in Alberta. If they don't have a location in Alberta, just what/where you be working?
