Congregation Knesseth Israel, Orthodox synagogue in Junction district, Toronto, Canada

Congregation Knesseth Israel, known as the Junction Shul, is an Orthodox synagogue at 56 Maria Street in Toronto's Junction neighbourhood. Its modest red brick facade has little ornamentation, a double-side staircase leads to two heavy wooden doors, and circular windows on three sides are divided into eighteen segments for chai, the Hebrew word for life. The interior follows a traditional Eastern European style, with a three-sided women's gallery on the top floor and the Torah ark against the eastern wall.

The congregation was founded in 1909 by Jewish immigrants, largely from Russia and Poland, who first held services in a house at 303 Maria Street. In 1911 the land at 56 Maria Street was bought for $520, and the synagogue, designed by James Augustus Ellis of Ellis and Connery, was dedicated on September 8, 1912; services began in 1913. Founding members and their families supplied bartered labour and donated funds, and the congregation founded Lambton Hills Cemetery in 1910.

The name comes from Hebrew meaning "Community of Israel". The interior layout follows Eastern European Jewish traditions, with the women's gallery positioned above the main prayer space facing the Torah ark.

The building sits on Maria Street in an accessible neighborhood and is easy to spot among residential streets. Services are typically held during holidays and important religious occasions throughout the year.

This is Toronto's oldest actively used synagogue and earned official heritage protection in 1984 under provincial law. The designation reflects its status as one of the city's most important markers of Jewish immigration history.
