Being Canadian I cannot see Canada being something else than US lapdog... how would the US react if we say no ? It would not take long to be officially part of it. It's just that it's more convenient to the US that we are still there.Xi personally insisted to Biden that Meng Wanzhou be released, thus she was release. Now that's what you call leave no one behind.
Also in light of this, we can all see how much this case was about Canada following the law vs Canada being US lapdog, as if we needed any more evidence.
