That's a tough one and I think only you can do the risk analysis. If you end up in the ER/hospital in the US, you are going to be paying a LOT of money for it, but then again, what are the chances, and are you able to pay out of pocket in any case? I know a lot of people coming from the UK buy it as a regular thing. Best to ask a Canadian crowd, not people from the US, because our insurance works very differently than yours.
