June 5, 2015 – The Mercedes of Lewis Hamilton and Nico Rosberg dominated Friday morning’s opening practice for the Formula 1 Grand Prix du Canada 2015, the world champion heading his team mate by 0.415s around Montreal’s Circuit Gilles Villeneuve. Their nearest rival was Lotus’s Romain Grosjean, the Frenchman finishing 1.5s down on Hamilton’s benchmark, and from there on the times were very tight, with around a second covering the next ten drivers.
