Ummm, Eastern Canada has taken imports of oil and gas due to the logistics of transfering crude from West to East across the country. As for ‘large’ amounts of oil and gas being exported to this region from Russia, I’m going to have to ask for some citation on that. Canadian imports of gas and oil were minimal back in the 70’s. It may have bumped up a bit after 1973 due to the US oil export ban. If anything the trade balance with Russia was the other way as we were exporting significant amounts of wheat as the country was unable to grow enough to feed its citizens.
