			 The Mercedes driver put Monaco disappointment behind him to set the 
			pace in a dry morning session before the heavens opened in the 
			afternoon and rendered the Circuit Gilles Villeneuve undriveable. 
 Hamilton was caught out in the deluge after going out on 
			intermediate tyres, a mere passenger as he braked into the hairpin 
			turn 10 with the car carrying straight on into the barriers at 
			reduced speed.
 
 The red flags came out with about 40 minutes remaining, 10 minutes 
			after the rain first started falling.
 
 "The ending might have been so-so but it's generally been a pretty 
			good day," said Hamilton.
 
 "I made a couple of mistakes -- pushing too hard and going over the 
			kerbs at the final chicane and then what happened at the end there.
 
 "Looking at the replays, I wasn't going that fast. But it was like 
			sheet ice into Turn 10 so the car aquaplaned and I went off," he 
			added.
 
			
			 
			Mercedes technical head Paddy Lowe said the car had also suffered 
			some minor damage to the rear of the car caused by the recovery 
			tractor swinging it around but all would be well for Saturday's 
			qualifying.
 If the times meant little, Hamilton still needed the morale boost 
			after a pitstop blunder cost him a surefire win in Monaco 12 days 
			ago and handed victory to team mate Nico Rosberg instead.
 
 His fastest lap in the morning of one minute 16.212 seconds was 
			0.415 quicker than Rosberg's fastest effort, and he improved that in 
			the afternoon to 1:15.988 despite crunching over the kerbs.
 
 Mercedes were again the team to beat, at a track whose long 
			straights reward engine performance but put a heavy burden on 
			brakes, but Ferrari also looked competitive.
 
 Hamilton, a three-times Canadian GP winner who leads Rosberg by 10 
			points after six races, had a late spin at the hairpin before lunch 
			but without consequence.

			Mercedes-engined cars filled the top four slots in the cloudy 
			opening session, after morning rain, with Romain Grosjean's 
			third-placed Lotus more than one and a half seconds slower than 
			Hamilton 
			Ferrari's Sebastian Vettel was fifth fastest, behind Nico 
			Hulkenberg's Force India, and then second in the afternoon with team 
			mate Kimi Raikkonen third ahead of Rosberg.
 "I don't know exactly where we are with our speed but for sure 
			Ferrari seems to be a threat. They were very quick today," said 
			Rosberg.
 
 Fernando Alonso, still chasing his first points of the season, was 
			ninth in the morning for Honda-powered McLaren while Dutch 
			17-year-old Max Verstappen was 10th for Renault-engined Toro Rosso.
 
 Verstappen's Spanish rookie team mate Carlos Sainz had a more 
			troubled first session and had to be pushed back to the garage after 
			stopping at the end of the pitlane. He also spun earlier in the 
			morning.
