Peacefully on Friday February 19, 2021 at the Oakville Trafalgar Memorial Hospital in his 90 ^th year.  Don was a dedicated supporter of the Canadian Children's Optimist Foundation and its predecessor, the Optimist International Foundation of Canada.  His contribution to CCOF has left a legacy.  Don was made an honorary member of the Corporation.  He is spoken about with respect, reverence and admiration.  He commenced membership of the Oakville Optimist Club in 1977.  Through his tenure he held many club and district leadership positions – most notably as District Chair of the Essay Contest, helping to establish the Bursaries program for senior students in the Oakville community.  Prior to his work in Oakville, Don had been a charter member of the Montreal-Cote-des-Neiges Optimist Club having held many positions, while contributing to the successful drum and bugle marching band.  Don retired from a career in the Treasury Department of Canadian Pacific, a job that allowed him to become well travelled.  Memorably, in the mid 1960's Don worked as a goal judge for the NHL and rubbed shoulders with some of the great Canadian hockey legends.  Donald MacDonald, never hindered by the "Two Solitudes" strived to help young people.  The Canadian Children's Optimist Foundation grieves the loss of a believer, supporter and example of living out the Optimist Creed.
