R v Ellis, 2009 ONCA 483 – (Gillese):

[38] In my view, “territorial jurisdiction” in s. 504 of the Criminal Code refers to the entire province of Ontario.

[39] Pursuant to s. 17(1) of the Justices of the Peace Act, justices have jurisdiction throughout Ontario. The fact that the Courts of Justice Act divides Ontario into regions for administrative purposes does not alter the jurisdiction conferred on justices by s. 504 of the Criminal Code. As Aitken J. stated in Hackett at para. 15, “[t]he regions created under the Courts of Justice Act are created for administrative purposes related to the administration of justice in the province; they are not created for jurisdictional purposes.”
