Church, Basilica, Cathedral… Here are the Differences
People sometimes refer to “Notre-Dame Cathedral of Montreal,” but this is incorrect. While the city does have a cathedral in its downtown area, and a cathedral can sometimes be a basilica, a parish can have a basilica even without a bishop. Let's clarify these commonly confused ecclesiastical titles!

The Church: The General Term
Any building dedicated to Christian worship is considered a church, whether tiny or monumental. In canon law, there is no distinction in this regard.
The Cathedral: The Bishop’s Seat
The word cathedral comes from the Latin cathedra (chair). A cathedral is the mother church of a diocese; it houses the seat of the bishop or archbishop.
In Montreal, this role belongs to Mary Queen of the World Cathedral, located on René-Lévesque Boulevard, not to Notre-Dame Basilica, which stands on Place d’Armes in Old Montreal.
The Basilica: An Honorary Title
The Pope grants the title of basilica to a church of exceptional historical, artistic, or spiritual significance. In 1982, Pope John Paul II elevated Notre-Dame Church of Montreal to the rank of minor basilica, recognizing its heritage role and liturgical influence. The title does not imply a resident prelate or a specific canonical territory.
Can a Church Hold More Than One Title?
A church can be both a cathedral and a basilica; meaning it serves as the bishop’s seat and holds historical importance. This is the case with St. John Lateran in Rome. This is not the case with Notre-Dame, which is a basilica but not a cathedral, since the archbishop’s seat is at Mary Queen of the World.
Why the Ongoing Confusion?
The size of the buildings often influences public perception. With 24-meter vaults, 65-meter towers, and one million visitors per year, it’s easy to assume that a structure like Notre-Dame could not be a “mere” basilica. Add to that the frequent use of the word cathedral in media when referring to any large religious building, and the misunderstanding continues.
