This is the 2017-18 Greater Ontario Junior Hockey League season. This was the league's 68th season overall dating back to the Eastern Junior B Hockey League, Metro Junior A Hockey League, and the Western Junior B Hockey League in 1950. The league has used the Greater Ontario Junior Hockey League name since 2007 when 3 leagues (Mid-Western Junior Hockey League, Golden Horseshoe Junior Hockey League and Western Ontario Hockey League) merged to form the present league.
- During the final round of the Sutherland Cup playoffs the Cambridge Winter Hawks announced they were severing their ties with the Ontario Hockey Association, possibly in response to the OHA denying the league's application to be elevated to the Junior A level. This would be a de-facto withdrawal from the league as membership in the OHA is required to be a member in an OHA sanctioned league.
- The Buffalo Regals relocated to the Buffalo State Sports Arena on the campus of Buffalo State College.
- In May 2017 it was announced that the Lambton Shores Predators were planning on moving out of Forest to move to Komoka, Ontario for the 2017-18 season The move had already been approved by the league and the OHA. The final approval of Middlesex Centre Wellness and Recreation Complex which met June 21st was the final step in the move. Two junior C level teams (Mount Brydges Bulldogs and Lambeth Lancers) were also reportedly interested in moving to Komoka. The team was re-branded as the Komoka Kings.
- On April 18, 2018 it was announced on the league website that the Ancaster Avalanche would be relocating to the Dave Andreychuk Mountain Arena in Hamilton, Ontario and would be renamed the Hamilton Kilty B's after the former Hamilton Kilty B's who were renamed the Hamilton Red Wings in 2002 and in 2015 moved to Markham, Ontario and became the Markham Royals.
- On May 8, 2018 the Ontario Hockey Association approves the relocation of the Guelph Hurricanes to Cambridge, Ontario. The team will play out of the Galt Arena Gardens for the 2018-19 season. The team was originally known as the Hesper Shamrocks and later Cambridge Shamrocks when they were established back around 1960. The team played in Cambridge until 1982 when they moved to Guelph. It was announced May 11th that the team will be renamed the Cambridge Redhawks. They will replace the Cambridge Winter Hawks who withdrew from the Ontario Hockey Association and by default the Greater Ontario Junior Hockey League after the 2016-17 season.
- The Caledonia Corvairs requested a one-year leave of absence for the 2018-19 season after completion of the 2017-18 season.
- On June 17, 2018 it was announced the Milton Icehawks franchise of the Ontario Junior Hockey League would be moving to Brantford and would take the 99ers name. The future of the present GOJHL team has not been decided but they are planning on staying put for the 2018-19 season pending a meeting with Ontario Hockey Federation officials. Both teams have the same owner.
