Allowing only US and Canada will be be a manual whitelist nightmare and will likely result in some unreachability.

A while ago, I tried to block China. The attack profile lowered a little bit, but I did not feel my network was safer. 
Looks kind of futile to me.
The bots are everywhere, blocking entire countries does not reduce the risk much.

I totally believe in the "my network, my rules" thing though. I do not provide Internet access to the public so what I 
deliver is my call.
At any given time I blacklist between 30K and 100K prefixes, motsly /32s.
