I am not very religious but I like their liturgical music, they have a wonderful choir and organist during the main Sunday morning service. It is a very ethnically-diverse congregation which is nice to see and they are open to everybody, whether you are a regular or just a visitor, gay, straight or omnisexual, black, white or green. The building is typically Anglican, this means Engish Neo-Gothic, it is open most of the time and there is no admission fees, so unlike the other two main houses of worship in Montreal.
You can also go and use their restroom if it's an emergency and you are nearby
