Having to wait until he was 19-years-old to start racing, Norman Jennings made his karting debut in 1978. He won class championships at the North Halton Kart Club in 1981 to begin a stretch of full-time seasons at the club, regional, national and international levels. He competed in 160 kart races over a nine-year span, recording 82 podiums and 116 Top-Five finishes, while winning championships in 1985 and 1987.

Jennings was one of two Canadians to compete in the Yamaha Challenge at the 1986 FIA-CIK World Karting Championships. He raced for Ultra Kart Team in the 1988 Ontario Kart Racing Association (OKRA) season and for Kart Klinic, in OKRA and Can-Am Series events, in 1989 and 1990. He then worked as a mechanic for Kart Klinic, where his Ultra Kart Team mechanic, Marilou Whaling, was now the driver. The team won the OKRA championship in 1992.

Following 195 kart races over 18 years, Jennings concluded his driving career and took on leadership roles in the sport. He became the first National Karting Steward for ASN Canada FIA in 1997 and was Chief Steward for OKRA regional events from 1998 to 2005. He worked closely with Paul Cooke at ASN Canada FIA from 1999 to 2019, participating in training sessions and meetings, where he helped with the creation and updates of national regulations.

Jennings held official roles at various events over the years, including being the Chief Steward for the ASN Canadian Karting Championships from 1999 to 2019. Most recently, he’s worked as Chief Steward for the Motomaster Ron Fellows Karting Championship, since 2019, and became the GDS ASN Canada National Karting Steward in 2020.
