Cartier Square Drill Hall

Cartier Square Drill Hall is a military training building in downtown Ottawa featuring a large central hall with two mansard towers and five tall Italianate windows on its front. The grounds include a parade square used for training and community events.

The building was constructed in 1879 under architect Thomas Seaton Scott as a key training center for soldiers preparing for conflict. It served as a crucial facility during major armed engagements throughout Canadian history.

The Officers' Mess holds military artifacts and regimental silver that tell the story of Canadian armed forces traditions and values over generations.

The location features a public parade square where military and community activities take place seasonally. It sits in an accessible downtown area and welcomes visitors during various ceremonial gatherings.

During summer months, the Ceremonial Guard begins their daily march from this location toward Parliament Hill for the Changing of the Guard ceremony. This daily procession draws crowds of observers who gather to watch the spectacle unfold.
