The Personality Disorders Service, part of Providence Care Mental Health Community Services, offers the Managing Powerful Emotions Group: “a 12-week (90-minute) psycho-educational group offered several times a year for individuals who have significant challenges with tolerating their distress and regulating their emotions and behaviour” (source) as well as other groups and programs.
You can view a list groups and programs offered by the Personality Disorder Service here.
To access this service, you will need a referral from a physician. You can find the physician referral form here.
(Programs of course may change over time. If you find any of the links no longer work or any info is out of date, let me know and I will try to update the information.)
