This Byzantine-style church dominates the corner of Rue St-Urbain and Rue St-Viateur. Its dome and soaring turret make it one of the more unusual examples of church architecture in Montréal. Intriguing elements include the massive dome with a depiction of St Michael vanquishing the seven-headed serpent (representing the seven deadly sins), figures of descending angels (representing the fallen angels cast into hell) painted on the pendentives, and the shamrocks hidden in the design elements.

Completed in 1915, St Michel served a mostly Irish community up through the 1960s. Today the church serves a largely Polish community, the latest wave of immigrants to the area.
