The comparable aircraft is the more modern E-7 Wedgetail, which has many features that are superior for Canada's use case (notably including range and NORAD integration). https://en.wikipedia.org/wiki/Boeing_E-7_Wedgetail

Canada has unfortunately been in conflict with Boeing since before either of Trump's terms, originally triggered by Boeing's trade complaints regarding Bombardier's government subsidies.

is norad integration actually important?

norad might not exist in 5-10 years

Canada has little used for airborne early warning outside of NORAD; the country has little independent air defense, and has not performed any foreign air superiority missions since the Cold Warz
