The big corporations limit their locations that they accept Bitcoin until they're 100% sure about where they can and can't trade it, Overstock for example accepted it in the U.S and now they're moving to worldwide, it's all just because the laws are different in each country.
Canadian bitcoin laws aren't much different than US. if dell is scared of dealing bitcoin here then they are a bunch of panzies.
Canada is somewhat more strict then the US is in regards to bitcoin regulations. I think there would be very few situations when something would be illegal in Canada that is not illegal in the US, but I am sure there are examples.
I do however think this is likely some kind of glitch or oversight on dell's part. I think it would be more effective to notify them via social media as the "higher ups" are more likely to see what is happening in social media then what is happening in the webs chats
