There are many possibilities for children of all abilities to enjoy summer camp. The best-known one is the Easter Seals Summer Camp, but there are many more options for both day and overnight camp opportunities.
Also find complete listings of BCCA accredited camps at the BC Camping Association website. They have a good list of hints and tips, including this one, "…the people who direct the camp are far more important than the equipment, buildings, and facilities advertised."
Many Disability-centred non-profits also sponsor summer camps for children with specific disabilities. Check out the organization that supports your child’s disability and see what they may be offering this year. For example the Cerebral Palsy Association of BC offers funding for children with CP to attend camp and the Canadian Cancer Society has Camp Goodtimes for children and teens living with cancer.
