The majority of crude oil imports into eastern Canada are now coming from the United States. They used to be from offshore, from a variety of countries including Saudi Arabia, Nigeria, and so on. There are still imports from all of those offshore countries, but the proportion has changed, and now the United States is the major supplier.
A few years ago the United States exported no crude oil to Canada, so that's a new market for American producers. I mentioned it as an example of how access to markets benefits all three countries in NAFTA. For people in Quebec and New Brunswick, that means that much of the gasoline they're putting in their cars comes from the United States but some of it is also coming from Saudi Arabia, Nigeria, and other places.
