Eastern Canada actually has access to natural gas from out west, via a facility in Sarnia, which gets the gas from Michigan.
You're probably familiar with the situation regarding the pipeline's viability, and the political and environmental concerns inMichigan around one of the three Great Lakes. As a supply source, its future is uncertain.
There was an attempt in the past to build a plant in Quebec, on the St. Lawrence River, but the problem was not so much the feedstock, but rather, the size of the investment required. What's more, in Quebec—and I assume it's the same in Ontario—heavy industrial projects can be very challenging because of all the environmental restrictions and the political landscape, which is very much geared towards reducing GHGs. All that to say, the project wasn't necessarily well received here, in Quebec. It was a very serious attempt a few years back, but it didn't get off the ground for the reasons I just mentioned.
