McLaren's Jenson Button has conceded it will be vital he qualifies better in Canada, if he is to stand any chance of scoring decent points.

Button has managed to notch up just two points in the last three races and having failed to make it through to the final phase of qualifying in both Spain and Monaco, he knows that is something he cannot afford to keep doing, if he is to stand any chance of getting back into championship contention and cutting the 31-point deficit to current championship leader, Fernando Alonso.

Button took a sensational win at the Circuit Gilles Villeneuve 12 months ago and a repeat victory would be timely now to kick start his faltering F1 2012 title bid.

"Obviously, returning to Montreal will be an extremely proud and happy moment for me," he commented.

"My win there last year was one of those rare occasions when everything just came right - it's still hard to believe that I was running in last place past half-distance and yet still managed to come through and take victory on the final lap. The memories of that win will always be with me.

"Montreal is always a race I look forward to though, anyway. The city has such a great vibe to it, the people are friendly and extremely welcoming and the fans are incredibly passionate.

"It's the perfect place to go racing and you can feel the excitement building literally as soon as you step off the plane.

"Next weekend, though, it's going to be important to get a handle on the car in qualifying. At the last two races, Q2 hasn't gone my way, so, no matter what pace you have in the race, you're still compromised on Sunday afternoon, particularly as the pack is so tightly bunched at the moment.

"My aim will be to have a stronger qualifying performance and to be able to build on that in the race."
