Systems Thinking Ontario is an group centered mostly in Toronto. Meetings (originally in-person, going online during the pandemic, and returning as mixed ever since) for 11 months of each year since 2012.

Much of the activity has been through the support of Graduate Studies at OCADU in downtown Toronto. Affiliates, friends and original sponsors involved faculty and students at University of Toronto and York University.

Upcoming meetings and the history of artifacts are maintained at https://wiki.st-on.org . There's a discussion group (mostly for meeting announcement reminders) at [https://groups.google.com/d/forum/st-on](https://groups.google.com/d/forum/st-on .) .
