Legally speaking? Almost certainly not.
(2) Every one commits treason who, in Canada,
(a) uses force or violence for the purpose of overthrowing the government of Canada or a province;
(b) without lawful authority, communicates or makes available to an agent of a state other than Canada, military or scientific information or any sketch, plan, model, article, note or document of a military or scientific character that he knows or ought to know may be used by that state for a purpose prejudicial to the safety or defence of Canada;
(c) conspires with any person to commit high treason or to do anything mentioned in paragraph (a);
(d) forms an intention to do anything that is high treason or that is mentioned in paragraph (a) and manifests that intention by an overt act; or
(e) conspires with any person to do anything mentioned in paragraph (b) or forms an intention to do anything mentioned in paragraph (b) and manifests that intention by an overt act.
I think there would have to be an actual military buildup to make that stick.
To be clear, I'm more than happy to call them colliquially treasonous...I just don't think elected officials should be throwing the term around too casually.
