The Community of Port Severn is situated at the mouth of the Severn River, Ontario, on Georgian Bay and it is actually divided by the river, into two small communities. South of the river the community is administered by the County of Simcoe and the community north of the river, is the seat of government for the Township of Georgian Bay, which is one of the six area Municipalities that comprise the District Municipality of Muskoka.

The southerly community has a fine Hotel, equipped with an excellent dining room, several marinas, grocery stores, restaurants and snack bars, and a liquor store. This community is served by private wells and has no urban water or sewerage services.

Port Severn was settled about the middle of the nineteenth century. At that time a saw mill, boarding houses and homes were constructed. It quickly grew into a small hamlet and a busy Georgian Bay port.

The community of Port Severn, in Georgian Bay Township, has been provided, by the District, with an excellent piped water and sanitary sewerage system, which at this time serves only part of the community, but it is designed so that it is capable of almost unlimited expansion to permit orderly growth for the community, well into the future. The rather small urban area contains the municipal offices, a museum, a community centre, marina facilities above the Trent Severn Canal Locks, a golf course, numerous mobile home parks, camping facilities, a service station/restaurant facility, where a bus service provides transportation three times a day each way on the Toronto to Sudbury route.

In the urban section there are a number of fine residential areas containing, as well as waterfront homes, many that are sited on beautifully wooded lots set in secluded locations.
