What is on in Ontario
Dates move every year, so we point to the calendars that the organizers keep current instead of copying them.
Ontario observes Mountain Time, an hour ahead of most of Oregon, so event times on official calendars may be Mountain Time. Check the time zone before you drive over.
Official calendars
- City of Ontario community calendar lists city events and meetings.
- Four Rivers Cultural Center events lists concerts, theater, exhibits and lectures at the nonprofit center.
- Ontario Community Library posts library programs.
- Ontario School District posts school dates.
- Treasure Valley Community College posts college events and dates.
