Housing co-ops are independent organizations and each one has its own application process. CHF BC does not accept applications for housing co-ops.
You can find listings for all co-ops at Find A Co-op. You can filter for co-ops with open waiting lists and other settings, and then read each co-op’s instructions for how to apply. Some co-ops will ask you to send a self-addressed stamped envelope (SASE), so they can mail you an application. Others will provide a downloadable application or a link to an external website where you can find an application. Still others will ask you to come to an orientation meeting to get an application.
You may also want to consider applying to a new Community Land Trust (CLT) co-op community and you can learn about which of those co-ops are accepting applications through cltrust.ca.
