Canadian interested in moving to UK. How are Brits generally with Canadian immigrants?

That's a bit bigger of a question than you might realize. Before Columbus, there were many nations, with different languages and distinct cultures. The Americas were about as varied and diverse as Europe, with likely more nations present. Many of whom were much more advanced than Europeans were willing to admit at the time, because it would invalidate the pretence used for the doctrine of discovery. If you need some examples of that, there were extensive trade networks. With copper mined on the north shore of Lake Superior being found as far south as Central America. And on the west coast, there was a practise of making 'clam gardens', where intertidal zones were engineered to produce ideal growing conditions for clams, and they were maintained and harvested in a manner to make them indefinitely sustainable, minimising disease, and maximizing the growth. That shows a knowledge of marine biology, engineering, and sustainability that doesn't match the idea of "stone age savages". I can give you a few book titles, but to get one that covers "everything" would be bigger than the entire Encyclopedia Britannica set ;) 1: *Native North America* \- Larry J. Zimmerman. This gives a broad overview of indigenous cultures including geographic spread and some history 2: *American Holocaust: The Conquest of the New World* \- David E, Stannard. This talks about the impact of European discovery and conquest. 3: *American Indian Languages: The Historical Linguistics of Native America* \- Lyle Campbell This is more of a technical book talking about how the language evolved. 4: *Clam Gardens: Aboriginal Mariculture on Canada's West Coast* \- Judith Williams This one is about the clam gardens I mentioned already 5: *They came for the Children* \- This is a report from the truth and reconciliation commission about the residential school system in Canada. It's available for free.
