Perhaps, in true Canadian fashion, we may agree to disagree on this.
I’d suggest that trade agreements favour some groups and hurt others and how one views them depends on the costs one pays and the benefits one receives. Who is listened to as we weigh these costs and benefits is a matter of political influence more than objective analysis and overall good.
And I would still suggest that without economic sovereignty, political sovereignty is not very meaningful and independent culture becomes merely symbolic. It has been a long time since any Canadian political party has suggested a real course of action to secure economic independence. This is because political parties listen to the money, and the money has little interest in Canada as anything but a marketing ploy and, sometimes, as a protected zone for particular industries that fear outside competition.
