2018-19 ACH Season

This is the 2018-19 Allan Cup Hockey Season. This is the league's 8th season under this name and 28th season overall. The league was previously known as Major League Hockey from 2004 to 2011, Ontario Senior AAA Hockey League from 2003 to 2004 and Southwestern Senior A Hockey League from 1990 to 2003.

Membership changes

 * Due to renovations at the J. L. Grightmire Arena, the Dundas Real McCoys relocated their home games to the Harry Howell Arena in Flamborough for 2017-18 and 2018-19. The McCoys played in Flamborough during the 1970’s at Beverley Arena and were known as the Rockton Real McCoys. Dundas was swept by Stoney Creek 4-0.  Due to no available ice time at Harry Howell Arena, Game 4 was relocated to The Haldimand Centre in Caledonia, Ontario.
 * The owner of the Brantford Blast, Peter Ham announced on July 12, 2018 that the team is for sale and he will not run the team for the 2018-19 season.  Ham has owned the team since 2002. It would be announced on September 10, 2018 that the team would not be playing for the 2018-19 season as they were unable to find a new owner. Sale of the team was announced on September 24, 2018. Unfortunately, it would be too late to get the team on the ice for 2018-19. The team should be returning to the ice for 2019-20. The owner of the Stoney Creek Generals will “co-own” both the Generals and the Blast to begin the 2019-20 Allan Cup season. There is hope to add a sixth team for the 2019-20 season to keep the league at an even number of franchises.
 * The Dundas Real McCoys will return to the J.L. Grightmire Arena (Market St Arena) for the 2019-20 ACH season.

Format
All four teams advance to the playoffs. Both rounds are best-of-seven. Due to a lack of teams in other regions of Ontario (Hockey Eastern Ontario and Hockey Northwestern Ontario), the playoff champion advances to the 2019 Allan Cup being held in Lacombe, Alberta as the Central region representative.
