The Bagg Street Shul or Beth Shloime (formally Congregation Temple Solomon) is an Orthodox synagogue operating in the Montreal
Plateau region of Montreal, Quebec
.In the early 1900s, fueled by heavy immigration, Jews established a large community in Montreal's Plateau region, around Saint Laurent Boulevard
The synagogue's building, a red-brick duplex on Clark Street, was constructed in 1899. The congregation purchased the building and moved there in 1922. The sanctuary seats 350. The Torah ark, marble staircase, pews, bimah furniture, and chandeliers were moved to the synagogue from the McGill
College location of the Shaar Hashomayim Synagogue. These items were purchased from the Shaar Hashomayim in 1918 for $1,500 ($20,200 today).
The Bagg Street Shul remains the oldest synagogue still operating with its original congregation in its original location in Quebec. The building is recognized as a religious historical site by the Quebec government.
