Mr. Chair, I think the member is talking about a period of time that is beyond the period of time for which we would make projections. I'll back up and provide the following answer.
Obviously, we're living in a period right now, with energy prices being what they are, when those inflows of revenues are substantially increasing our revenues and also the revenues of a number of provinces. Over time, as the world evolves towards a net-zero world—and obviously that's a world headed toward 2050 and there's a substantial period of time between now and then—as you say, what are we doing about revenues? My answer to that is that over time, as fossil fuels wind down, one of the challenges Canada will have is to develop alternative engines of growth.
I'll give you some numbers. Fossil fuels used to be about 34% of business investment in Canada. Recently, they've been about 10% or 11%. That has to be replaced by the building of new engines of growth, and from those engines of growth there will be revenues.
We don't regard the trend toward net zero as something that is necessarily a threat to the revenue stability of the federal government. The challenge is building the alternatives that will drive growth and prosperity in Canada as we do evolve to a net-zero economy.
