Grimsby is a town on Lake Ontario in the Niagara Region, Ontario, Canada. Grimsby is a part of the Hamilton Census Metropolitan Area. The majority of residents reside in the area bounded by Lake Ontario and the Niagara escarpment. The escarpment (colloquially known as 'the mountain') is home to a section of the Bruce Trail.Grimsby has experienced significant growth over the past decade as the midpoint between Hamilton and St. Catharines. In early 2011, Grimsby is expected to be the home of the West Niagara YMCA. Growth is limited by the natural boundaries of Lake Ontario and the Niagara Escarpment and has almost come to a stop as a result of the Greenbelt Plan [ ] which has permanently frozen Grimsby's urban boundary. Some residents feel that development is detrimental to the town as orchards close to the town centre are used for residential development; however, most of the orchards in Grimsby were replaced by houses between the 1950s and 1980s and very few orchards remain.Some notable attractions in Grimsby are the local skatepark, the Grimsby Museum, the Grimsby Public Library, the Grimsby Public Art Gallery, the Danish Church and the hockey arena (Peach King Centre), home of the Grimsby Peach Kings.
