Q

It is very unlikely that the Gulf of Mexico oil spill would impact Maritime Canada and the north eastern USA because the Gulf Stream moves east away from the coast as it moves northward (and, eastward towards Iceland and Europe. By the time the Gulf Stream is off Canada's east coast it is abour 400 nautical miles west of the coastline. Also, the prevailing currents along the Canadian Continental Shelf, off eastern Canada, flow south (part of the Labrador current). The southward flow, I suspect, would be prevailing throughout the Gulf of Maine to Cape Cod.
