I can't give you a number. It depends on what's available in the market. It would require a much broader study.
However, I could mention a few specific examples. I mentioned the Browning-BAR earlier. This is a semi-iautomatic firearm that is very popular in Canada. I also mentioned the Remington 742 and the Remington 740 Woodmaster, semi-automatic weapons widely used in Canada. On the basis of Mr. Mendicino's answer, they were on the list because they were available or marketed in other countries with higher-capacity magazines.
So I don't have a number for you, but there are a lot of them.
