If you can volunteer, but don't know when or how, sign up! If you can volunteer, but it depends on the date and time of the event, sign up! If you are contemplating volunteering, but need more information, sign up! As events come and we find we need volunteers, we'll advise you of the event, date, and times we need you and YOU get to decide if you can or want to volunteer. We provide the events and let you know. Your volunteer time is controlled by YOU. A valid/current CBE Clearance from Calgary Police Services may or mat not be required, depending on the volunteer position needed. We will advise when one is required at each volunteer call out.
