The O Sign

Lore & Background

The O has been the gravitational centre of Ottawa hockey identity for well over a century. From the original Ottawa Senators of the early 20th century through the modern NHL franchise, the circular O has persisted as the city's hockey sigil. It is a letter that is also a shape, a shape that is also a ring, a ring that is also a promise: that this city, this team, this community holds itself together in a circle, unbroken. Fans do not say 'the logo.' They say 'the O.' It is a word, a thing, a feeling.

In the arena, the O is everywhere at once. It is the centre-ice logo skated over a thousand times a season. It is the giant illuminated letter that blazes during the national anthem and the player introductions. It is the letter on the foam fingers, the painted faces, the hand-painted signs in the upper bowl. When the crowd chants, the O is the visual anchor that the sound orbits around. It gives the noise a shape. It makes a building full of strangers into a single organism with one letter for a name.

There is a particular Ottawa pride in the O that goes beyond sports. It is the city's initial. It is the letter in 'Ottawa.' In a metropolis that is often described as quiet, procedural, and understated, the O is the one bold, declarative mark. It says: we are here, we are round, we are not going anywhere. The Senators' O Sign is, in the end, the city talking to itself in a voice it can hear over the ice.

In Their Own Story

The arena is half-full and the lights are still warming up. A woman in the 200-level has painted a thick red O on her forearm with a marker, the ink still tacky, and she keeps turning her wrist to check the edges. Around her, a group of men in matching red jerseys are arguing about a trade that happened three seasons ago, their voices flat and certain, the way Ottawa people argue about things that are already settled. The jumbotron flickers to life and the O fills the screen, enormous, red on black, and the whole section exhales at once, a small collective sound like a door closing on a cold night. A kid in the row ahead pulls a foam O from his backpack and holds it up. His mother takes a photo. The puck drops. The O on the ice is skated over, skated over, skated over, a hundred times before anyone notices it, because it is the ground, the given, the thing you stand on without looking down.

Reader's Guide

Canadian Tire Centre is a mid-size NHL arena in the south end of Ottawa, and the O Sign is woven into its visual language at every level. The centre-ice logo is a large red O on a white background, visible from every seat. The jumbotron displays the O during the anthem, intermissions, and goal celebrations. The ribbon boards carry the O alongside sponsor signage, and the concourse is lined with retail displays of O-branded merchandise: caps, scarves, foam fingers, and the ubiquitous red O pin.

During games, fans perform a handful of rituals that orbit the O. The most common is the 'O wave,' where a section of the crowd raises foam O fingers in a rolling motion during key sequences. After a goal, the upper bowl often erupts with a sustained roar while pointing at the jumbotron's O. On cold-weather nights, fans in the lower bowl will hold up hand-painted cardboard O signs, a tradition that has no single origin but feels ancient.

The team integrates with Ottawa's local culture through community events in the arena, youth hockey clinics in the city's neighbourhoods, and the visible presence of the O in downtown Ottawa during the season—on banners, on the bus shelters, on the side of the team bus. The O is not just a team mark; it is a civic watermark, as much a part of the city's visual identity as the Parliament buildings or the Rideau Canal.

Did You Know?

• The letter O is the only element of the Senators' branding that has remained constant across the franchise's entire history, from the original 19th-century club through the modern NHL team.
• Ottawa's nickname as a city is sometimes simply 'the O,' used by locals and media as a shorthand that predates any specific team or logo.
• The centre-ice O at Canadian Tire Centre is resurfaced and repainted multiple times per season to maintain its visibility under the ice, making it one of the most frequently recreated logos in the NHL.
• In Ottawa, the O appears on municipal signage, city branding, and tourism materials independent of hockey, meaning the symbol belongs to the city as much as to the team.
