Canada isn't all that much different from the USA with respect to the topic of circumcision. There are a few interesting statistics that are worth pointing out when it comes to that topic.
First up on the list would be the risk of contracting an STD. Believe it or not, but an uncircumcised guy as the top of the sexual relation is statistically 200% more likely to contract an STD through the pocket under the foreskin than that of a circumcised guy. This is largely due to the fact that the foreskin creates a trap (or pocket) for lack of a better term where bacteria and other such foreign substances can get trapped, particularly if you do not clean under the foreskin. By this same token, speaking as a guy who has not had the little snip snip, I can attest that if you are not very careful to clean out under the foreskin very well on a regular basis, you'll find yourself at an increased risk and frequency of infections such as strep throat bacteria or yeast infections under the foreskin, which can become rather painful.
On the flip side of that, although the risk of running around with a germ trap is much higher with an uncircumcised penis, there are also drawbacks to getting the little snip snip. One of the biggest downsides that I know of to having the foreskin removed is that a number of people that I know who have had it done later on in life report that the sensitivity in the head of their penis is either non-existent or otherwise severely reduced by comparison after having the foreskin removed. The other most common down side that I have heard of is in cases where the doctor, moyle, etc that is doing the circumcision doesn't do it correctly, thus taking off a little too much skin. In this type of situation, getting an erection can actually be painful as the remainder of the skin gets stretched out much more than it otherwise should, which can cause painful sensations if the procedure is not done correctly. Sadly, it is my understanding that this down side is rather common.
