Can the OPP give me a ticket in London?

There is a common myth in Ontario that the OPP do not have authority to issue tickets in a city with its own police force. However, this is not true. The Ontario Provincial Police (OPP) have jurisdiction across all of Ontario. Though they are most commonly seen on the highway, a police officer in Ontario has jurisdiction to lay a charge anywhere in Ontario if they have witnessed an offence. Some cities in Canada have their own police force, while others contract out to the OPP or federal police (RCMP). In Ontario, you can receive a traffic ticket from the city police, OPP, or RCMP anywhere in the province if they witness you breaking the law.
