Calendar of Events

CIS Ontario educators and staff should also view the Student Event Calendar for rehearsal and event dates, and the CISAA Key Dates, that may have an impact on their schedule.

The CISAA Key Dates below include season start and end dates and dates for playoffs and championships. To view the entire CISAA schedule, including all individual team information see our CISAA Schedule & Standings webpage.

These are CIS Ontario network-run events. They are organized and managed by network leads and volunteers. The best way to stay on top of what's happening in our CIS Ontario networks is to login to CISO Connect and join the networks applicable to you.

This calendar is populated as we receive information from schools about their 2024-2025 Open Houses. You may also wish to view our Member School Directory page to view the independent schools in your area.

Member schools, if you would like to request an open house be added to the School Open Houses calendar, please look below and click the green plus icon just above the calendar list.

Member School Events are not official CIS Ontario events (organized and managed by our office). We are happy to highlight events for our members schools as requested. If you would like to request that your event be added to the Member School Events calendar, please look below and click the green plus + icon just above and to the right of the event list below. Include a description and a link to an event page on your website, if possible. Once your event has been approved to appear in the calendar it will also be added to our news and social media feeds. (We do not promote member school events through email to our member lists.) If your event is for the CIS Ontario member community only, or if you do not see a green + icon, please email Laryssa at ltysonlebar@cisontario.ca to arrange the posting of it to our member portal.
