City councilors have historically reacted to public pressure and have a sensitivity to their constituents’ needs as they rely on their votes, so by mobilizing and engaging the community to respond at key moments to calls to action, they will create a critical mass of pressure that will result in a majority vote on the focus issues of their campaign.

As of May 2023, the network has representatives from more than 150 individuals and groups from 20 wards and more than 50 neighborhoods.

To create and protect a healthier and more livable city, CAFES’s objective is to promote effective environmental action in the local community and at the municipal level.

CAFES communicates frequently with the Ottawa Federation of Citizens’ Associations (FCA) and is a member of it.

They support local groups’ initiatives to make Ottawa a better, healthier, and more livable place by collaborating with groups like Ecology Ottawa, Forêt Capital Forest, the Greenspace Alliance of Canada’s Capital, Waste Watch Ottawa, City for All Women (CAWI), and Synapcity.
