Canada's relationship with the US is fairly typical of a small (by population) country next to a larger one that speaks the same (or similar) language. You'll find the same anxiety of influence in Ireland, Belgium, Pakistan and New Zealand.
BTW HP is originally British, not American, although it is now produced by Heinz in the Netherlands. I am an avid consumer.
Superficially, the two countries are very similar but Canadian values are not as far out on the individualistic and religious side: life, liberty and the pursuit of happiness versus peace, order and good government. We are closer to Western Europe when it comes to religion, taxes, government etc. Broadly speaking, you can see a similar, gradual change in US values as you move north and to the east and west coasts. Lord knows what the global smartphone/internet experiment will do to both cultures.
