Welcome to the Ontario Branch site!

The Ontario Branch of CWRA began operating informally in the early 1970s, conducting conferences and workshops and in 1991 the Ontario Branch was officially incorporated.

Operations of the Branch are managed by a board composed of not less than ten directors, who are elected at the annual meeting by the members. All provincial directors are CWRA members. Each director is elected to hold office for a period of one year. The directors are responsible for the election/appointment of officers and committees.

If you’re interested in getting involved in Branch activities, we’d love to hear from you! You can get in touch with the Ontario Branch by emailing on@cwra.org.
