The theme for the 2023 convention, WE ARE NO LONGER ALONE, celebrates what we are discovering in a deeper way:  following our recent time of physical isolation, as well as the emotional/psychological/spiritual isolation that accompanies the family disease of alcoholism, we can turn to one another and share our experience, our strength, and our hope on the path of recovery.

We hope you will join us as we gather in person this June!

NOTE:  All attendees will be asked to adhere to any provincial public health guidelines that may be in place at the time of the convention.

Trillium flyer with program:


Ontario South’s Trillium Convention occurred in Toronto yearly from 1992 to 2013, with a final gathering in Richmond Hill in 2016. Each gathering took place over a weekend in early summer – a conference of various speakers, workshops, and social events organized and hosted by Al-Anon and Alateen, with a full companion program for our AA guests. Truly a Celebration of our Recovery!

After years of dormancy, Trillium will re-blossom in 2023! Following changes to the Trillium Charter, decided upon at Ontario South Assembly in 2021, as well as developments in technology that allow planning meetings to take place virtually, so arose an opportunity to learn from/build upon our experience and tap into a new energy of trusted servants.
