This is the 2018-19 Keystone Junior Hockey League season. This is the league's 46th season overall and 16th under its' present name. The league was previously known as the Manitoba Junior B Hockey League from 1974 to 2004. With the withdrawal of the Winnipeg area teams the league is now comprised of all First Nations sponsored teams.
- The Arborg Ice Dawgs, Lundar Falcons (senior), North Winnipeg Satelites, St. Malo Warriors, and Selkirk Fishermen withdrew from the league to form the Capital Region Junior Hockey League, citing travel costs and travel safety in light of the Humboldt Broncos bus crash. As of August 24, 2018 the new league has not been sanctioned by Hockey Manitoba but a meeting was scheduled for September 6th with the issue to be addressed at the meeting.
- On October 14, 2018 the Fisher River Hawks would announce they would be sitting the season out.
- A team from Nelson House, Manitoba has been accepted into the league, the team would later be named the Nelson House Flames. The team would not be on the schedule when the league started play in the fall. The team would be re-accepted into the league in May of 2019 for the 2019-20 season, but under the NCN Flames name.

The provincial championship will not be held this year and the league finalist will participate in the 2019 Keystone Cup as the Peguis Juniors are hosting the event and automatically qualify.

- Peguis Juniors defeated OCN Storm 3 games to 2
Baldy Northcott Trophy Playoffs
As the Baldy Northcott Trophy is the Manitoba provincial Junior B championship trophy; a new trophy will likely be used for the league playoff championship for both the Capital Region Junior Hockey League and the Keystone Junior Hockey League. No provincial championship will be held this year, the playoff champion was to be the KJHL league representatives for the Keystone Cup. However, the host of the Keystone Cup won the league playoffs, so the runner-up represents the league instead.
