Merritton is both a distinct community within and a council ward of St. Catharines, Ontario, Canada. It was named after William Hamilton Merritt, a prominent local entrepreneur and founder of the Welland Canal Company. Until 1858, Merritton was named Welland City, but exchanged names that year with Merrittsville (Today's Welland City), when that town became the "seat" of Welland county.
Merritton is often referred to as The Heart of St. Catharines, due in large part to the location. Prior to amalgamation in 1960 which saw the original city of St. Catharines absorb several satellite towns, Merritton was a separate entity (along with Grantham and Port Dalhousie). To this day, residents maintain a sense of distinct community identity. The original town hall, on Merritt St., once the City of St. Catharines Museum, is now home to the St. Catharines Senior's Centre.
Merritton has developed a significant system of community organizations, including the Merritton Lions, who oversee the Community Days Parade (formerly known as the Labour Day parade) and Carnival, the Dunc Schooley Memorial Pool, and several other sports and recreation facilities. It is also home to one of St. Catharines' arenas, and a Community Centre.
As a former industrial center on the Welland Canal, Merritton retains a small yet impressive number of heritage sites. Among them are the Merritton Tunnel (under the third Welland Canal), remnants of the three previous Welland Canals and several early industrial ruins, and The Keg restaurant, which is housed in the former Independent Rubber Company / Merritton Cotton Mills Annex. The area has undergone a major infrastructure facelift involving the re-alignment of Glendale Avenue and the replacement of the Merritt Street Bridge. It is also experiencing a significant increase in residential construction, especially on property designated as brownfield by the city.
