Hi, please respond, need advice, any help in finding a job for winter roads/ ice roads trucking in Canada. My husband is currently in Alberta, Edmonton-Yellowknife. He signed contract with Westcan for winter roads trucking and end up there doing just regular roads (with regular pay...) He went there from Toronto, Ontario...Now he is thinking of going back...Please suggest what to do in such situation and are there any other companies who hire for winter roads. He is 10+ years experienced trucker.
