Nico Rosberg expressed disappointment with his performance in Canada as he missed out on pole position to team-mate Lewis Hamilton.
Rosberg, who claimed top spot at the circuit in 2014, was three-tenths of a second slower than the Briton and will start Sunday's race from second place.
"It was the best way to sum it up," he said, referring to his comment about a 'rubbish' end to qualifying via team radio.
"I was feeling good then at the end it didn’t come together at all, struggling with grip and this and that, didn’t work out and we need to analyse where it was, especially on the first set [of tyres], [then I] didn’t go quicker, disappointing, fair play to Lewis."
Rosberg was nonetheless encouraged to still end up on the front row of the grid.
"I had a bad qualifying but I’m still second on the grid thanks to the car we have and that gives me hope for tomorrow, it’s possible to overtake here so it’s still to play for tomorrow, but I’m disappointed with today," he concluded.
