Bob MacDonald competed in multiple Ontario regional road racing series and the Firestone/Firehawk Endurance Championship, but his greatest achievements in motorsport came through his sales role at Sony of Canada. He was an integral part of the company’s sponsorship of motorsports through race cars, billboards, print advertising and television, where the Sony Handycam was used for in-car footage.

Several notable drivers were supported by Sony of Canada in their racing efforts, including Robin Buck, Paul Tracy, Ron Fellows and Scott Maxwell. MacDonald worked to bring Sony sponsorship to the grassroots level as well, through local karting clubs and an annual event held by the Simcoe Kart Club. He served on multiple boards of directors at the grassroots level.

MacDonald also worked directly with tracks and events to include Sony banners and product support at notable circuits, including the Toronto and Vancouver street courses and Canadian Tire Motorsport Park.
