Malcolm was born on March 12, 1984

In 1994, when Malcolm was ten years old, he started karting in a small championship at Shannonville, in which he finished second. From there, he went up the karting ladder, winning multiple national events, as well as a North American Karting Championship event north of Montreal (Rotax Max).

When Malcolm turned 16, he switched over to sports car racing, and raced a Toyota MR2. With a few top-five finishes in Ontario Challenge Cup (OCC) GT3, mid-season a Mazda RX7 Turbo II was prepared, and it was raced in GT2. In 2001, the focus was set on the OCC GT2 Championship. With three wins, Malcolm took the points championship by a wide margin. He was also awarded the Stirling Moss Award for being BARC's most successful driver of 2001.

Over the winter, a 2000 Corvette for the 2002 Canada GT Challenge Cup was prepared. Through the season, Malcolm had many podium finishes, and held the points lead until the final race, in which the engine blew and the championship was lost. The car was displayed at many events throughout the year, including a fundraiser for the protection of abused women, as well as Canada Day celebrations. He was awarded Canadian Driver of the Year by the Canadian Race Communications Association, and was given a Civic Award by the Municipality of Prince Edward. That winter, a 422 cubic inch engine was built for the Corvette, producing an estimated 585 horsepower, and Malcolm won the Super GT category of the 2003 CASC Touring-GT Championship.

From 2004 to 2007, Malcolm raced the Corvette in Ontario and Quebec, scoring many wins and claiming two Quebec GT1 championships, and placing runner-up in Ontario GT1.

In 2008, Malcolm's first pro race was a struggle, where he and the team owner of the Nissan 350Z fought an ill-handling car to a 13th place finish in Trois-Rivieres. Unfortunately, a lack of sponsorship precluded any other racing for the 2008 season.

Similarly, in 2009, sponsorship could only be secured for one race in the NASCAR Canadian Tire Series. Malcolm drove the RUSH-HD Dodge Avenger for Jim Bray Autosport. Despite never driving a NCATS stock car before his first and only practice session for the weekend, Malcolm was 12th fastest in wet practice. His qualifying was a struggle, having to learn how the car worked and what the track was like in the dry in only four laps; he ended up 19th out of 34 cars, qualifying ahead of his more experienced team-mate. In the race, Malcolm battled through the pack, got punted off the track, fought back, had a spin and fought back again, only to have a mechanical failure with 12 laps to go.

Malcolm has also been involved in other sports besides racing. He swam competitively for almost ten years, and competed with his school's relay team at the Ontario provincial championships (OFSAA). He continues to swim during the winters to keep in shape for racing as well as running and cycling in the summer.
