Trefoil Guild

West Ottawa Wanderers Trefoil Guild HikeTrefoil Guild membership is for members from age 30 to whenever! Belonging to a Trefoil Guild is a great way to connect socially with other adult members of Guiding, as well as a way to support youth members and Guiders through such activities as fundraising or event planning. 

Membership in the Trefoil Guild is open to currently fully-screened members of Girl Guides of Canada who are over the age of 30. All members are entitled to wear the Trefoil Guild Pin with the appropriate adult uniform or the pin may be worn out of uniform.

Not a member of Girl Guides of Canada? You can apply to join us! Trefoil Guild members follow the same screening process as volunteers. Learn more about adult membership and the screening process.
