There are other crown corporations, for instance the Federal Bridge Corporation Limited. That corporation owns the bridges over the St. Lawrence, in Cornwall, the Thousand Islands, and Sarnia. The police services on these bridges are paid for by that corporation. Those services may be provided by the municipal police or by a provincial organization. It varies. Since there is no federal police force for this sort of thing, those are the services that are used.
