it saw a number of accidents; Senna came out to win again. 1991 saw a dramatic finale in which Nigel Mansell's Williams failed on the very last lap only a few corners from the finish line; Nelson Piquet took his 23rd and final F1 victory in a Benetton. Austrian Gerhard Berger won the 1992 event after the dominant Mansell spun off after a collision with Berger's teammate Senna. Alain Prost won the 1993 event while fending off a spirited drive from Senna, and in response to the Imola tragedies, the 1994 event saw the very fast Droit du Casino curve being turned into a chicane. German Michael Schumacher won this event. Ferrari's Jean Alesi won the 1995 edition, which occurred on his 31st birthday and which would be the only win of his career. Alesi had inherited the lead when Michael Schumacher pitted with electrical problems and Damon Hill's hydraulics failed. The victory was a popular one for Alesi, particularly after several unrewarded drives the year before, namely in Italy. Alesi's win at Montreal was voted the most popular race victory of the season by many, as it was the number 27 Ferrari—once belonging to the famous Gilles Villeneuve at his much loved home Grand Prix. Schumacher gave Alesi a lift back to the pits after Alesi's car ran out of fuel just before the Pits Hairpin. The Canadian Grand Prix race had grown in importance around this time; the demise of Grands Prix in Detroit, Phoenix and Mexico City meant that it had been the only North American Grand Prix round since 1993 and would continue to be the only round in North America up until 2000, and again from 2008 to 2011 after yet another demise of the United States Grand Prix, this time at Indianapolis. It was also one of two races in the entire Americas, the other being the Brazilian Grand Prix, although the Argentine Grand Prix had returned for 4 brief years from 1995 to 1998. The 1996 race saw the Casino corner removed and the layout changed; the run from the hairpin at the bottom of the circuit was turned into a straight. Briton Damon Hill won this event, and the 1997 race was stopped early due to a crash involving Olivier Panis. He was sidelined for nine races and some see it as a turning point in the career of the 1996 Monaco
