Lewis returns to top track

LEWIS Hamilton is back at his happiest stomping ground this weekend when he seeks to extend his world championship lead with a recordequalling seventh triumph at the Canadian Grand Prix.

The defending four-time champion, who leads nearest rival and fellow four-time champion Sebastian Vettel by 14 points after six races, claimed his maiden Formula One win at the Circuit Gilles Villeneuve in 2007.

Since then Hamilton has added five more wins.
