Kubica took advantage of Hamilton's error to seal his maiden win
BMW Sauber's Robert Kubica said he would try to win the Formula One title after his maiden victory in Canada put him in the world championship lead.
The Pole admitted he was helped by Lewis Hamilton crashing his McLaren, but said his own team deserved credit.
"If you are the leader after seven races then you clearly have a car that can win races," the 23-year-old said.
"I hope the team will give me the maximum and I will give my maximum to fight for it."
Kubica put in a copybook performance in Montreal on a crumbling track that caught out many of his rivals.
And the retirement of Hamilton and Ferrari's Kimi Raikkonen, who was taken out by the Englishman in a freak pit-lane collision, cleared the way for the Polish driver to win.
Kubica admitted that Hamilton was quicker on Sunday, and that work remained if BMW were to win in normal circumstances.
The goal was to win a Grand Prix this season, and we've done it
"We are working on it. Our target this year was to win a Grand Prix and we have done it," he said.
"But clearly Hamilton was the quickest here - he made a mistake though and he paid for it.
"I have to thank him that he chose Kimi and not me."
Kubica's victory came on the same track on which he had suffered a horrific crash last year.
"It's been an incredible year but also a struggling year," he said.
"Last season I was struggling a lot, but we managed to fix some issues that were not working - and I'm doing pretty well this season.
"I think it shows how much I was struggling last season but I'm very happy winning in Canada where I had a big shunt last season. It's something amazing.
"The goal was to win a Grand Prix this season, and we've done it."
