I used to work for Amazon... Their key warehouses are located in the delta, and one of the main ones (an Amazon Robotics building, YVR4) is in Tsawwassen. If all that is cut off with the rest of the country... I'm glad I don't work for them anymore, because they must be tearing their hair out right now: there will be no Black Friday in Canada, or folks will have to be okay with waiting weeks for their shopping to arrive.
