100in1day Ottawa

What is 100in1Day?

100In1day is a global festival of civic engagement and a growing movement that is changing how people interact with their cities.  Originating in Bogota, Colombia, and spreading to cities around the world, the festival has inspired citizen-driven change in cities through small urban interventions. The spirit of 100in1day is democratic, imaginative and empowering. The festival is a platform for citizens to activate ideas to make their city healthier, happier and more inspired, one initiative at a time.   

Powered by Synapcity, with support from United Way Ottawa and community partners, 100in1day is coming to Ottawa for the first time this year! We're excited by the possibilities and here to support you.  

By taking part in this festival, you have the opportunity to share ideas that you've always wanted to see in Ottawa or try out a new idea and have it profiled as part of this big day of civic engagement. 

How can I participate?

Multiple ways to participate:

  • Lead an intervention on June 3rd. Work with a group of friends to think, plan and organize. Register your event as soon as possible to maximize promotion. 
  • Sign up to volunteer as an organizer, help out on June 3d, provide resources, promote the festival or mentor. 
  • Provide in-kind or financial support to the festival. The festival is a grassroots, city-building project. It is inspiring, creative and built on volunteerism, goodwill, local expertise and diversity. Partner with us to make it a huge success.

Who can Participate?

Anyone can participate! Old or young, new to the city, or lifetime resident, June 3rd is a day of possibility - where you can re-imagine your city. If you've ever had an idea for your neighbourhood or community, here is your 'social licence' to put it into action. 

What if I am Already Planning a Community Event or Festival on June 3rd?

Existing festivals and community events planned for June 3rd are encouraged to join 100in1day if they take place outdoors, in public spaces and are free and open to anyone. By submitting the event or festival as part of 100in1day, it's an opportunity to promote the event to a larger audience, network with others, and participate in a city-wide, global movement.
