You have tried that twice before, 1776 and 1812 or thereabouts and we rather forcefully and with some great loss of American lives said "no thanks."
You are completely wrong about cultural values. Canadians DO NOT speak English as a first language, 35% speak French as thei first and sometimes only language, to et anywhere here you have to speak both.
There is NO cultural connection beyond the media. If any American want to try to understand that try reading a Canadian philosopher named John Ralston Saul

We are about as similar as blackberries and roses. The US was founded on war, spends a good majority of its income on war and war machines, while Canada spends its money on health care and social programs. Americans arm themselves against each other, Canadians arm peacekeepers and look out for one another. We deplore your violence and racism and you would NOT like how we deal with people who want to walk around with a gun. You would not like our policing as we watched in horror the military equipment rolled out against your own citizens, an appalling display of fear.
The US is divided along race, black white, and political, lines a growing schism leading to more and more violence in the streets. In Canada we never refer to race, but nationality, we have no red people, yellow people, black people, brown people, or white people, we have Canadians, a land where there has never been a race riot, we riot over the very important things in life, hockey.
While you tout Norad, Canadians are increasingly questioning our traditional role with Amerika, especially in light of the fact you've been killing and bombing people for 14 years and now have Iraq V3.0 with another 5 to 15 years of war there.
Canadians have a higher standard of living than the US, better education, better health care, and we get along, Asians, Indians, Africans and even], gasp!, Muslims. Why would we want to give that up so Americans can have access to our resources?
Please keep out.
