If the shipment originates or terminates in the US, the party brokering the load, whether it be a broker or a carrier, must be in possession of a Property Brokers Licence and maintain a 75K surety bond as a condition of that licence. If the shipment is strictly within Canada, anything goes. If a carrier has to pass the load over to another carrier for completion, one would like to think that the ethical course of action would be to advise the original broker of his intent, and to obtain their consent. Not too sure how many times that actually happens in the "real world". A competent freight brokerage should monitor customs documents to ensure that the carrier crossing the border is the same carrier they tendered the load to.
