Moosonee is a city in Northern Ontario, referred to as the "Gateway to the North" and is Ontario's only saltwater port where goods are transferred from trains to aircraft and barges to more northerly communities. Although it is on the same latitude (51 N) as Calgary, Saskatoon, London (UK), and Berlin, it is still an isolated community as there is no road access
The site of Mossonee was originally settled by Annie Hardisty and her two daughters in 1900. However, the place was not fully developed until 1903 when a crew of 21 fur traders of Revillon Frères arrived to establish the Moose River Post, which became their most important location and was quickly expanded with a staff house, carpenter's shop, warehouse, and sawmill. Although this outpost was prosperous, it remained isolated with supply ships only arriving once a year from Montreal and mail only arriving four times a year. Scows that travelled along the Pagwachuan, Kenogami, and Albany Rivers from Pagwa were the only supply lines for Moose River Falls until 1932 when the Temiskaming and Northern Ontario Railway was extended to Moose River Falls from Cochrane and the town was renamed Moosonee from the Cree word Moosoneek meaning "at the Moose (River)".
In 1936, Revillon Frères sold its Canadian operations to the Hudson's Bay Company and the Moosonee post closed. The HBC also exited the fur trade and opened a retail store in Moosonee (now Northern Store part of The North West Company). With the end of the fur trade business, Moosonee's economy became centered on transportation.
In 1962, Moosonee became the site of RCAF Station Moosonee that was part of NORAD's Pinetree Line chain of radar stations. It closed in 1975 and some of its buildings were used by the Town after the closure, including the base swimming pool and recreation centre.
In 1968, the town was classified as a Development Area Board. In November 2000, it was incorporated as the Town of Moosonee.
The Ontario Northland Railway's Polar Bear Express passenger train from Cochrane is the main method of access to Moosonee, which operates six trains per week during the summer months and five trains per week during the rest of the year.
There is no road access into Moosonee except for winter ice roads to Moose Factory, Fort Albany, Kashechewan and Attawapiskat, which are mostly used by trucks for mining operations. The nearest all-season road is 150 km south in Otter Rapids.
Air Creebec provides scheduled air service from Moosonee airport to Attawapiskat, Fort Albany, Kashechewan, Kingston, Peawanuck, Timmins, and Waskaganish as well as general aviation and air charter services for propeller and turboprop aircraft only. Seaplanes arrive and depart from the Moosonee Water Aerodrome.
