after a fatal accident at a Formula Ford support race and by the time it started, it was raining heavily. Jackie Stewart took victory easily in a Tyrrell from Swede Ronnie Peterson in a March. 1972 saw Mosport upgraded with new safety features, and Stewart won again. 1973 was an interesting event; like the race 2 years previous it was a rain-soaked event. Austrian new-boy Niki Lauda in a BRM took the lead from Peterson in a Lotus on Lap 3, Lauda led until the 20th lap when he came to change tires; there was considerable confusion after François Cevert and Jody Scheckter collided on Lap 33 leading to a bungled pace car interlude after which things became very confused as the pace car failed to pick up the leader and allowed those ahead to gain almost a lap. All this meant that Briton Jackie Oliver ended up in the lead with American Peter Revson second and Frenchman Jean-Pierre Beltoise third. Of these three Revson had the most competitive car and so eventually moved into the lead and led all the way to the flag while Peterson's Brazilian teammate Emerson Fittipaldi charged to try to make up for lost ground and overtook Oliver and Beltoise in the closing laps to grab second. For hours after the race confusion reigned but eventually it was confirmed that Revson was the winner- thanks to a lucky break when the pace car came out. The 1974 event saw Fittipaldi win while his championship rivals Clay Regazzoni finished 2nd and Jody Scheckter crashed heavily after a brake failure on his Tyrrell. There was no 1975 event, and the 1976 event was one where Briton James Hunt found out that his 9 points from Brands Hatch were taken away and he was disqualified; Hunt won the Canadian Grand Prix event that year, driving furiously throughout the race. 1977 was the race where French-Canadian Gilles Villeneuve made his debut for Ferrari. But concerns about the bumpy Mosport Park's safety arose when Briton Ian Ashley had a horrendous accident while cresting a bumpy rise. Ashley's Hesketh flipped over the Armco guardrails and went into a television tower. The German-born Englishman was seriously injured and safety operations to rescue him were inefficient and time-consuming; and the lack of safety at Mosport was underlined when Jochen Mass lost control of his McLaren and hit a guardrail that virtually flattened upon
