Statistics Canada does publish projections of Canada's population at the Canada and provincial levels, but we make a distinction between projections and forecasts. A forecast might be what you believe is going to happen. A projection is simply saying if this happens or that happens, this is what results.
The problem is we don't know what's going to happen, particularly at the level of the provinces and territories where internal migration can have a huge impact on populations. The simple, natural, increase in immigration would yield one set of projections, but more important, what we couldn't ever anticipate would be the economic factor. So I really don't think I could responsibly produce a set of numbers that I would say you could be reasonably confident would hold true for the next 10 years. I simply don't think that's possible, not by Statistics Canada. Braver people might be willing to do that, but we wouldn't have the confidence to produce that kind of number.
