It also served as the home of the Niagara Falls Canucks, a team in the Greater Ontario Junior B Hockey League. The city has built the Gale Centre to replace the Memorial Arena. The Gale Centre has a similar capacity in one of the four ice pads, with the other three having a modest capacity for recreational hockey and skating league purposes. The Gale Centre has become a community center, of sorts, for ice-based activities with offices for figure skating and house-league hockey organizations.

It is not to be confused with the former La Salle Junior High School, which is now the La Salle Preparatory School, also located in Niagara Falls.

The school was located at the eastern front end of the large property and on prime real estate on Military Road almost directly opposite Wegmans, which is a busy shopping corridor which also includes the expanding Fashion Outlets Mall.
