In 1999, the successful Canada GT Challenge Cup entered its third season. Sanctioned by ASN Canada FIA, it was a twelve-round series of races one-hour in length. Drivers competed at Mosport International Raceway, Shannonville Motorsport Park and Le Circuit Mont-Tremblant.

  • Mosport International Raceway – BARC Spring Sprints
  • Mosport International Raceway – BEMC Spring Trophy Races
  • Mosport International Raceway – Victoria Day Trans-Am Weekend
  • Shannonville Motorsport Park – CRDA Shootout
  • Shannonville Motorsport Park - DAC Trillium Trophy Races
  • Shannonville Motorsport Park – TLMC-MCO Canaska Cup
  • Le Circuit Mont Tremblant – Mountain Thunder Weekend
  • Mosport International Raceway – BARC Grand Prix of Ontario
  • Mosport International Raceway – C.A.G. 250 Weekend
  • Mosport International Raceway – CRDA-SCCA Nationals
  • Mosport International Raceway – BEMC Indian Summer Trophy Races
  • Mosport International Raceway – Panoz Motorsports Celebration

A wide range of vehicles was eligible for the series – FIA GT, Professional Sportscar GTS & GT, SCCA Improved Touring, GT1, GT2 & Trans Am and ASA Stock Car. The list of ineligible cars was much shorter – Sports Racers, Ground Effects Cars and Showroom Stock.

There were two classes (GT1 and GT2) based on qualifying and race lap times:

Mosport International Raceway

  • GT1 – Faster than 1:31.999
  • GT2 – Slower than 1:32.000

Shannonville Motorsport Park

  • GT1 – Faster than 1:10.999
  • GT2 – Slower than 1:11.000

If a GT2 driver broke out of the time bracket, they would be moved to GT1.

One or more drivers could compete in a car. However, the second driver had to complete either twenty minutes or one-third of the total race laps to earn points. The races also included a mandatory one-minute pit stop during green flag conditions.

The penultimate round of the 1999 Canada GT Challenge Cup was held at Mosport International Raceway during the BEMC Indian Summer Trophy Race weekend. Drivers would compete in a one-hour contest around the ten turn 2.459-mile road course.

The start of the penultimate round of the 1999 Canada GT Challenge Cup. Leading the field of twenty-sixth competitors into Mosport International Raceway’s corner one is the pole-sitter, James Holtom, in the No. 93 Georgian Bay Motorsports Chevrolet Camaro. Behind Holtom is the other front-row starter, John Brenner, driving the No. 81 Chevrolet Monte Carlo. In third place is the No. 00 Porsche of Klaus Bytzek.
The third-fastest time in qualifying would result in Klaus Bytzek’s worst starting position of the year. Bytzek was gridded behind his main rival James Holtom and the Chevrolet Monte Carlo of John Brenner. However, the always quick Holtom encountered mechanical issues and Brenner retired with a differential failure. The driver of the No. 00 Porsche 911 GT1 Evo dominated the event and won by a three-lap margin.
An accident early in the season prevented Kirk Spencer from defending his Canada GT Challenge Cup GT2 title. It took several rounds before the No. 24 Spencer Racing Chevrolet Camaro was competitive and he started collecting podium results. Spencer scored his first class victory of the year in race ten. At the BEMC event, Spencer qualified second in GT2 and won the category; he finished third overall.
The final GT1 race result sheet at the BEMC Indian Summer Trophy Races looked quite different from those earlier in the year. The high attrition rate allowed some unfamiliar faces to step on the podium. As usual, Klaus Bytzek stood on the top step of the rostrum. He was joined by second-place finisher Keith Carter. Carter, driving the No. 30 Chevrolet Camaro, qualified sixth fastest on the way to his runner-up result.
Round nine GT2 category winner, Blaise Csida, stepped aside to allow Mark Swain to pilot the No. 7 Martini sponsored Chevrolet Corvette. Swain was a regular in CASC Ontario Regional events, but this was his first start in the Canada GT Challenge Cup. He qualified eighteenth in the twenty-six car field. The one-hour contest gave Swain plenty of time to move to the front and he finished second in class.
Canadian endurance veteran Gunter Schmidt and Peter Carpenko campaigned the No. 36 Greenbelt Motors Volkswagen Corrado VR6. They often finished in the top ten, with their best result being a pair of fourth-place results in GT2 and Shannonville Motorsport Park and Le Circuit Mont-Tremblant. The duo started round eleven twentieth and finished fifth overall, which earned the final spot on the class podium.
The two biggest beneficiaries of the high attrition rate in the GT1 category were Rudy Bartling and Rick Franczak. They shared the No. 39 Porsche 911 and started the season in the GT2 class, where the duo collected a pair of third-place results at Shannonville. However, they went under the GT2 lap time and were bumped to GT1. They finished third in class at the penultimate race, albeit five laps behind the winner.
