This charity provides free Grief Counselling Services to dying children and to children whose parent or sibling is dying. They offer a Youth Bereavement Support Group for 13-18 yr olds, and their Family Support Program offers a variety of free events and activities to families who have experienced the death of an immediate family member including Family Night events which happen once a month and offer creative outlets for emotional expression and connection to the memory of loved ones.

And 4 times a year they offer Information Sessions with topics ranging from ‘Talking to your Kids about Death and Dying‘ to ‘Explaining Suicide and Overdose Death to Children‘.

Dr. Jay’s also operates Camp Erin - a weekend-long overnight bereavement camp in Muskoka for children and youth aged 6-17 from the GTA and military families from across Canada.
