Interested in becoming an Associate of SSG?

Associates and prospective Associates approach SSG from time to time with projects that require additional support or capacity.

Contact us for application instructions. Applying to be an Associate and applying for a job with SSG are very different things. Please bear this in mind when expressing your interest in working with us.

Yes, we’re a worker co-operative.

We fundamentally differ from other types of businesses in three key ways:

  • The purpose for our organization is to provide stable and meaningful work for our members.

  • Each member has an equal say in decision-making.

  • Surplus (i.e. profit) is invested into improving the well-being of communities.

Advocacy and representation

We are actively engaged in Co-ops and Mutuals Canada, Canadian Worker Co-op Federation (CWCF), Co-operatives UK, and participate in UN negotiations and engagement.

Walking the Talk

We are dedicated to addressing social and environmental justice—through our work and in our own operations.
Internally, we do this in three ways.

  • By selecting projects that challenge the status quo and progress our knowledge and action on climate change.

  • By preparing briefs or writing letters targeting specific issues, the old fashioned way.

  • We publish our reports using the Creative Commons licensing agreement and our tools are open source with participation, use, adaptation and feedback encouraged.
