This is actually a pretty lame post. I really tried, I tried my very best to find information on how many people in Canada convert to Islam. This information is, as of today, simply not available to the public (or perhaps anyone).
But, I offer this as a cop-out. Information on the amount of people who convert to Islam in the United States. I think it reasonable to assume that the numbers would be very similar in Canada.
There's this one number, that since the mid 90's, around
20,000 people per year in the US convert to Islam.
You see this one a lot.* This is a very small number for a country of 300 million people. It's only 0.000067% per annum. There's also a similar one of 25,000 the New York Times used once. That's still only 0.000083%. Using the upper-end number of 0.000083%, I think we can reasonably estimate that around 2600 people in Canada convert to Islam every year, being so similar to the US. But this would be "overblown" according to "theologians and demographers" referenced by the
Seattle Post-Intelligencer.
Conversion is a fairly insignificant area of growth for Islam in Canada, the main reason for growth is immigration. Muslim immigration to Canada is high. (
Canadian Census data). In 1991 there were 253,300 Muslims in Canada. In 2001 there were 579,600. Of those 326,600 new Muslims, around 270,000 immigrated to Canada, and so, assuming 2600 converted each year, around 53,400 were born and stayed in Canada. It's impossible to get a truly accurate birthrate from this. But if we assume both those numbers are distributed evenly throughout those ten years (which creates a little inaccuracy for this purpose) and that the number emigrating from Canada is negligible (which may be true), we get a birthrate of around 21/1000 per annum which is much higher than the
2006/2007 Canadian total of 10.9/1000, though it seems very reasonable.
Keeping that birthrate going from 2001 we would end up with 643,000 in 2006 from natural growth, and keeping the trusty 2600, we would have 656,000 from birth and conversions. The officials report there is an estimated population of 783,700 Muslims in Canada
in 2006. With our numbers, that would imply an immigration to Canada of about 127,000 in 5 years, which is pretty close to the rate of the official census amount of 270,000 in 10 years from 1991 to 2001. So the birthrate of 21/1000 per annum for Muslims in Canada seems like a reasonable estimate.
* You see this a lot though too: "Rates of conversion have gone up since 9/11!" As if to say, "Terrorism works!"
