I'd say arrest her and wait for the backlash then arrest those who commit crimes.

last thing you want is to set a precedent that everyone on a 'side' is a criminal. wait for the crimes.

it wouldn't hurt to string up a few of the traitors as well.

Here is the actual code (obviously from when Queen Elizabeth was Monarch):

High treason

46 (1) Every one commits high treason who, in Canada,

(a) kills or attempts to kill Her Majesty, or does her any bodily harm tending to death or destruction, maims or wounds her, or imprisons or restrains her;

(b) levies war against Canada or does any act preparatory thereto; or

(c) assists an enemy at war with Canada, or any armed forces against whom Canadian Forces are engaged in hostilities, whether or not a state of war exists between Canada and the country whose forces they are.

Treason

(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.

Recall that Danielle Smith visited Trump at Mar-A-Lago shortly after he was reelected to the Presidency of the USA, for a meeting with undisclosed purpose. Rumours indicated that she and Trump discussed Smith opening the way to allow Trump to seize control of Alberta, after which she would be installed as Governer of occupied Alberta. Everything that she has done since that meeting regarding this astroturfed referendum campaign is consistent with this rumour. Not proof, but highly suspicious.
