    • We walk through the cold and dark on February 26, 2022 to declare our concern for people who have no home and take shelter in nooks and crannies.

    • We walk for those whose days are a battle to house and feed their families and whose nights are filled with fear and frustration.

    • We walk for those driven from home by violence and abuse. And we walk for people overwhelmed by isolation, guilt, and despair.

    • We walk humbly, realizing that anyone can lose their footing and then lose everything else.

    • Each step we take brings someone closer to safety, health and home, as together, we raise funds for organizations whose commitment and work transforms peoples’ lives.

  • Camp Winston offers summer camp programs and weekend retreats throughout the year for campers aged 7-13 across Canada, as well as a Teen Program and weekend retreats for campers aged 14-17. Campers have a complex combination of neurobiological disorders, which include:

    •  Autism Spectrum Disorders       

    • Attention Deficit Hyperactivity Disorder       

    • Tourette’s Disorder       

    • Learning Disabilities       

    • Obsessive Compulsive Disorder and other anxiety disorders       

    • Oppositional Defiant Disorder

    Most of our campers experience two or more of these challenges and, in most cases, their condition is so severe they would not be welcome at another summer camp. At Camp Winston, everyone is welcome. Period.
