Established during Canada's centennial year of 1967 and named in honour of this, the 67's currently play their home games at TD Place Arena.

[3] They played their first game at their own arena, the Ottawa Civic Centre, on December 29, losing to the Montreal Junior Canadiens 4–2.

[1] They won their first playoff series over the Hamilton Red Wings in 1970–71, led by future Hockey Hall of Famer Denis Potvin on defence.

The 67's came close to playing at home in the Memorial Cup, as the Ottawa Civic Centre hosted the tournament that year.

[7] Leo Boivin was named as Long's successor as head coach of the 67's and Ross Tyrell as general manager on June 18.

During the late 1970s, Ottawa was led by scoring champions Peter Lee, Bobby Smith and Jim Fox and future Hockey Hall of Fame defenceman Doug Wilson.

[16][17] At the Memorial Cup in Kitchener, Ottawa faced the Laval Voisins, featuring Mario Lemieux, of the QMJHL and the Kamloops Jr. Oilers of the now renamed Western Hockey League (WHL).

[16] Creighton, Pang, Shaw, Cassidy, Jim Camazzola and Don McLaren of the 67's were all named to the tournament's all-star team.

[19] After the season ended, Kilrea left Ottawa to become an assistant coach in the National Hockey League (NHL) with the New York Islanders.

As hosts, they still took part in the Memorial Cup tournament and faced the Bulls, the Calgary Hitmen of the WHL and the Acadie–Bathurst Titan of the QMJHL.

The 67's beat the Belleville Bulls in the Memorial Cup semi-finals and went on to defeat the Calgary Hitmen in the final in a thrilling over-time game that saw Matt Zultek score the winning goal.

In the 2002–03 season, the 67's reached the OHL finals again, but fell to the eventual Memorial Cup champions Kitchener Rangers in five games.

Ottawa upset the Barrie Colts, Sudbury Wolves and Peterborough Petes to reach the finals versus the London Knights.

In the tournament, Ottawa faced the Knights, the Rimouski Océanic of the QMJHL, featuring Sidney Crosby, and the Kelowna Rockets of the WHL.

The 67's won the longest ever game played in the Memorial Cup tournament, when they beat the Rockets in double overtime.

[30] Andre Tourigny won OHL Coach of the Year award in 2018–19 leading the 67's to a 50–12–6 record and a franchise record-breaking 106 points.

[35] Dave Cameron is the 67's most recent recipient of the award, taking home the honours after leading the club to their record setting 51-win season in 2022–23.

Denis Potvin and Doug Wilson are the only Ottawa 67's alumni to be inducted into the Hockey Hall of Fame as players.

In keeping with their new "Hockey With Bite" slogan, it featured a logo with an angry puck, and a white background body with jagged red and black trim lines along the bottom and arms.

[39][40] However, the guest capacity reached as high as 10,449 for Ottawa Senators games, when the NHL team played in the arena while awaiting the construction of their own rink.

[43] In early February 2012, it was announced that the 67's would move to the Canadian Tire Centre for two seasons while renovations were finished at TD Place Arena.

This came as a result of delays in construction originally planned to allow the 67's to stay at TD Place through the rebuild but a closed site was needed to meet deadlines for NASL and CFL expansion.
