Section 477.3 — Criminal Code: Exercising powers of arrest, entry, etc.

Every power of arrest, entry, search or seizure or other power that could be exercised in Canada in respect of an act or omission referred to in section 477.1 may be exercised, in the circumstances referred to in that section, at the place or on board the ship or marine installation or structure, within the meaning of section 2 of the Oceans Act , where the act or omission occurred; or where hot pursuit has been commenced, at any place on the seas, other than a place that is part of the territorial sea of any other state. A justice or judge in any territorial division in Canada has jurisdiction to authorize an arrest, entry, search or seizure or an investigation or other ancillary matter related to an offence committed in or on the territorial sea of Canada or any area of the sea that forms part of the internal waters of Canada, or referred to in section 477.1 in the same manner as if the offence had been committed in that territorial division. Where an act or omission that is an offence by virtue only of section 477.1 is alleged to have been committed on board any ship registered outside Canada, the powers referred to in subsection (1) shall not be exercised outside Canada with respect to that act or omission without the consent of the Attorney General of Canada.
