I could jump in first on that. You're talking about energy east, which was cancelled by the proponent, TC Energy, in 2017. It would have had an all-Canadian route to get supply from western Canada, from Alberta and Saskatchewan, to refineries in Ontario and Quebec using an all-Canadian route. It would have used the existing TransCanada gas pipeline, converted it to oil and ensured that our supply didn't enter into the United States. It would have ensured that we weren't at risk for the United States' not letting the supply out or shutting it down.
The interesting thing is that the Enbridge main line, which was built in 1950, chose to use an American route at the time, as it was the most economical route and the easiest route to build a pipeline from an engineering perspective. It went through the United States to come back into Canada to Sarnia. Six years later, when the TransCanada main line was built, it was determined that Canada wanted an all-Canadian route to protect the security of supply. In 2017 we would have had an all-Canadian route under way called energy east. Unfortunately, that dream was cancelled.
