The Lakeshore Senior Baseball league officially affiliated with the Lakeshore Baseball Association (L.B.A.) at the end of the 2007 baseball season. The Lakeshore Senior Baseball league was looking for an easy, yet distinct acronym for the league’s new web-site domain, prior to the 2008 season. 

Historically, in 2002, the city of Montreal and all of the island’s suburbs had become known as the Montreal Urban Community (MUC). The transit system was called the MUCTC and all of the island’s police and fire departments were part of the MUC. Thus, the Lakeshore Senior Baseball league initially adopted the acronym MUCSLB (Montreal Urban Community Senior Lakeshore Baseball) league.  

The league’s name still reflected its total affiliation to the Lakeshore Baseball Association and thus, allowed adult baseball players from the cities of Baie d'Urfe, Ste-Anne de Bellevue, Senneville, Kirkland and Beaconsfield, a league of their own. The acronym also eliminated any confusion with the various adult softball leagues within Kirkland and Beaconsfield. 

The name of the Lakeshore Senior Baseball league is unique. It is the only independent adult recreational baseball league in Montreal. Well done Lakeshore Baseball Association
