Thank you for that. It's not my area of expertise, but I will make a comment.
I think when you start looking at the whole picture, at the royalties paid by companies--in Canada, it's only for natural gas--at the investments, and at the manufacturing in Ontario, which is directly related to the oil sands and natural gas, it's up to about 40%.
When you start looking at the overall investments by oil and gas companies, it is very significant. On the employment side, which is very significant, one of our issues will be a skill shortage. But clearly, I think the oil and gas companies have contributed significantly.
