On March 16, Little League International asked organizations to suspend all activities until at least May 11, 2020, to reduce the spread of COVID-19.

Based on City of Calgary and Alberta Provincial regulations, RMLL anticipates that regular season activities will be delayed until sometime after June 30th this year, subject to information and advice provided by Alberta Health Services, Little League Canada, and Little League International.

All 2020 registrants were sent a request to provide input on options to run a summer season. Thank you to the almost 300 people who completed the survey. The league will be sending out further information regarding the delayed season over the next few days.

One important note is that any players who want to withdraw can do so and will receive full refunds. Those who have asked if they can apply 2020 registration fees toward 2021, or who indicated they would like to donate 2020 registration fees to RMLL will also be permitted to do so.

Please check our website, RMLL's Twitter and Instagram pages, and your email for the most current updates and information on plans to run a "warm weather" baseball season this year.

See the LL FAQ page for more information.


Due to the recent global pandemic and the most recent decision by LL Canada to suspend all LL activities until at least May 11, 2020, this years RMLL Umpire Clinic has been cancelled. 

It is regretful, but out of an abundance of caution that we take this step.  It is my sincere hope that life will return to normalcy sooner rather than later and young people can get out and enjoy the great sport of baseball. 

Take care,

Jeff Anderson
