Manufacturing, because it's more tradable than other types of goods and services generally speaking, is one of the products for which we see more trading across provincial borders. I will say there's plenty of opportunity to improve domestic trade ties with the oil sands. We actually import more from outside the country than we do from other provinces into Alberta as a result of the oil sands. There are lots of opportunities to improve domestic supply chains.
It varies by region. The big manufacturing inputs going into the oil sands are things like steel, manufactured metal products, different types of machinery. The things that are very specific to the oil sands tend to occur in Alberta so there's definitely a cluster there associated with those things, but a lot of secondary things might come from elsewhere. For example, from Saskatchewan there's a fair amount of steel coming in and there's a fair amount of metal products coming from Ontario. Even out east the Michelin plant in Nova Scotia provides tires that go onto some of the vehicles that are used in the oil sands. It goes right across the country. It's tied to what's produced in the local regions and then how they've been able to link with Alberta.
As I said, 30% of the supply chain effects in terms of employment occur outside of Alberta. Ontario is the biggest beneficiary. They have half of that. B.C., Quebec, and the other prairie provinces each split the rest of that between them. The Atlantic ties are fairly small, to be honest. The biggest impact for most of the Atlantic provinces is the income remittances they get from people who are working temporarily in the region.
