But not only did Raikkonen's ninth-place finish Sunday drop him to third position for the year — he also had to endure the humiliation of being lapped by Vettel halfway through the race.
"We got a couple of points, but a bad weekend and a bad result," said the Finn, who saw Ferrari's Fernando Alonso slip past him in the drivers' rankings with a second-place result in Montreal.
"We lost the brakes (at) the beginning, maybe after three laps, and luckily they came back, but they were not very good."
Raikkonen, who won the 2007 world championship with Ferrari, felt he started well on Circuit Gilles Villeneuve before the brake problems cropped up. But things got even worse for him during a pit stop later in the race.
"They dropped the car and I lost quite a bit of time," said Raikkonen, who won the 2005 Canadian Grand Prix with McLaren.
"I don't know what happened."
The entire weekend proved to be a bumpy one for Raikkonen, who said the brake problems also caused headaches for him on Friday and Saturday. He struggled in qualifying and started 10th on the grid for the race after being penalized two spots Saturday for not leaving from the proper lane.
Then on Sunday, Vettel — the race leader and eventual winner — roared past him on the 34th lap of the 70-lap event.
"Most of my race was just following the cars in front and defending from those behind, so not the most enjoyable day nor the most enjoyable result," Raikkonen said.
Ferrari's Felipe Massa overtook him on the 69th lap, leaving the 33-year-old with a ninth-place finish and two points in the drivers' standings.
Those points represented personal victory for Raikkonen from his visit to Montreal. He completed his 24th consecutive race with at least a point, tying F1 legend Michael Schumacher.
Schumacher, however, pulled off the feat at a time when only drivers in the top eight places earned points. Since 2010, the top-10 positions earn results.
Raikkonen insisted the points-streak equalizer means little to him.
"I don't care about that," he said. "I care about scoring the points, but not about any records."
It's been a frustrating stretch for Raikkonen, who had a big start to the season by finishing in the top two spots in four of the first five races on the calendar.
But two weeks ago at the Monaco Grand Prix he was bumped by Sergio (Checo) Perez as the McLaren Mercedes driver tried to pass him on a chicane.
The damage caused Raikkonen to drop from fifth place to 10th and lose valuable championship points. Perez was later forced to retire with brake trouble.
A frustrated Raikkonen suggested after the Monaco Grand Prix that someone should "punch him in the face."
