There is, yes.
Three words - human rights violations.
And that's not counting all the other reasons to dislike and totally distrust China.
Actually, not true.

What pew research poll showed China better than the US in approval in Canada?
If I was in the minority, then yes, you're right, and I'd not like it but I'd go with it. But since it's likely that you're wrong about China...
I don't know, I won't know until the day comes. For now I just continue on continuing on, which includes worrying for my US friends and family and keep hoping that the US comes back to its senses and stops the bullshit it's doing now.
Been there, done that and walked away then, too. I've let the US go as much as I, personally, an amble to, by refusing to go there and buying anything but US when I have a choice. But the issue is, we DON'T have choices sometimes.
Honestly, I think if it came down to it, Canada WOULD walk away from the US if things got that bad. They're bad now, yes, but it's not to the level of so bad there is no changing/going back. There are enough people in the US who actually dislike how things are now that it can be changed back to sense. Cutting off our noses to spite or faces, or shooting ourselves in the foot, won't do squat at this point. Sometimes you need patience and this is one of those times.
