The process for extradition from Canada continues to have both a judicial and an executive phase. At the judicial phase,
a judge will determine if the conduct constitutes an offence in Canada and if there is sufficient evidence such that, had it occurred in Canada, the person would be committed to stand trial. At the executive phase, the Minister of Justice will decide whether or not to surrender, taking into account all of the circumstances and any applicable ground of refusal
