If I were to extrapolate current Muslim growth rates, which is just over 9% per year, the Muslim population of Canada by 2080 would be a ridiculous 273 million, so obviously I have based the 25-35 million estimate is based on a declining year over year growth rate.

The only question is by how much. But try this: take today's growth rate of 9% and decrease that by 0.1% per year up to 2080, 63 years from now.

You will arrive at 44 million. If you start at 8% growth today, you still see 24 million.

So use your own numbers.. By the way, look at the "natural growth rates" given for the decades preceding the current day. Those numbers of over 2% were due to larger family sizes which is interesting given that Muslim family sizes are approaching twice the non-Muslim Canadian average, even given today's cost of living.

Canada is indeed becoming more expensive. And, by 2080, give or take a few years, it is on track to becoming a Muslim majority nation.
