Sir Jackie Stewart has lauded Lewis Hamilton's maiden Formula 1 pole position in Montreal for today's Canadian Grand Prix as "terrific", though he warns the young Brit will need to keep his wits about him if he is to prevail in the race too.

The three-time world champion was at the Circuit Gilles Villeneuve to witness the 22-year-old's landmark achievement, and said he had been particularly marked by Hamilton's resilience in recovering from an earlier error to re-assert his authority.

"It was a terrific performance," the Scot told "To get pole position in only his sixth grand prix is pretty impressive.

"Until the end you honestly wouldn't have known if it was going to be a McLaren or a Ferrari on the top spot. Lewis made a mistake then pulled himself together to produce his best lap. That's very impressive and shows a certain maturity."

Stewart did, however, have some advisory words for the reigning GP2 champion, with particular regard to Montreal's notoriously tricky opening complex of corners as the drivers funnel their way into turns one and two almost as one directly after the lights go out.

"I think much depends on the first corner and first lap," he stressed. "That's one of the most important things, especially here."
