2017 CFL season

[6] The 2017 Canadian Football Hall of Fame inductees were announced during this week and the CFL and TSN photo shoot also took place here.

There was also an interactive Fan Festival, a head coach and general manager media event, and the CFL Rules and Competition Committee meetings, which normally take place in February.

For the fourth consecutive season, week 1 featured a Grey Cup rematch, with the defending champion Ottawa Redblacks hosting the Calgary Stampeders.

The Canadian Football Hall of Fame game took place on September 15, 2017, featuring the Hamilton Tiger-Cats hosting the Saskatchewan Roughriders.

[9] Kelvin Anderson, Anthony Calvillo, Mike O'Shea, and Geroy Simon were inducted as players while Stan Schwartz and Brian Towriss joined as builders.

O'Shea is the currently the head coach of the Winnipeg Blue Bombers, whose team had a bye that week, and he also played four seasons with the Tiger-Cats.

[10][11] Mosaic Stadium was declared "substantially completed" on August 31, 2016 and a test event featuring a football game between the Regina Rams and Saskatchewan Huskies was held on October 1, 2016.

The new service expanded coverage around the world to new markets including mainland Europe, Asia and Africa, totaling over 130 new countries.

Jim Lawson, the league's Chairman of the Board of Governors, assumed the duties of commissioner until a suitable replacement was found.

On November 7, 2016, the Montreal Alouettes released their 21-year general manager and sometime Vice President and head coach Jim Popp after two disappointing seasons in a row.

Popp joined the then brand-new Baltimore Stallions organization in 1994, and contributed to the revived Montreal team's current three Grey Cup championships and eight East Division titles over his tenure as general manager (as well as an additional Grey Cup and one South Division title in Baltimore); Popp was the last major legacy contributor from the CFL's American expansion of the 1990s.

[20] On December 14, 2016, the Alouettes held a press conference to announce Patrick Boivin as President and CEO and Kavis Reed as general manager.

[22] After six seasons as the general manager of the Argonauts and compiling a 49–59 record in that time span, Jim Barker was fired on January 24, 2017.

[25] The decision was made in large part because of a contract dispute and philosophical differences regarding increasing the media and fan accessibility of the team.

[26] Hervey had been the GM since the 2013 CFL season, and had led the team to a record of 40–32 (3–2 in playoffs) during that time, including winning the 103rd Grey Cup.

Scott Milanovich had been the head coach of the Argos for five seasons starting in 2012, leading the club to a record of 43–47 during his tenure.

Trestman was the head coach of the Montreal Alouettes from 2008 through 2012, with a record of 59–31, guiding the Als to back-to-back Grey Cup titles in 2009 and 2010.

[31] On August 24, 2017, midway through the 2017 season, Kent Austin stepped down as the head coach of the Hamilton Tiger-Cats (remaining with the team as vice president of football operations), and named June Jones his successor.

[38] On August 13, the league launched a suite of T-shirts with the moniker "Diversity is Strength / Diversité est synonyme de Force" in response to the riots in Charlottesville, Virginia.
