If you're using ebay.ca you won't see USA-only (or UK-only, Germany-only, etc) listings. You need to be on ebay.com AND not have your location set as Canada. You will then see many many more listings. If I see an auction I'm interested in, I send a message asking for the okay to bid. Over 90% of the time, the seller is fine with shipping to Canada.
In this case, although it would be poor etiquette, it might be worthwhile to buy first, ask permission later.

+1 to this. This is what I do. Being in Singapore, my options are severely limited so I'm forced to look out for good deals in multiple country ebay sites . I always ask the seller if it is ok to bid before I place my bid and most of the times, sellers are fine to ship overseas. Sometimes the cost of shipping is high but it may still be worth the while if the razor I'm interested in is rare or NOS; like the rare and NOS 1924 Olympic special that I purchased from ebay France and got it shipped to Singapore even though the shipping cost was a bit high.
