Star of the session: Vettel and Valtteri Bottas turned in good laps at the end of the session and deserve plaudits.
Villeneuve drove for Ferrari for five years, claiming six victories, before he was tragically killed in qualifying for the 1982 Belgian GP, and Vettel savoured claiming the Scuderia's first pole in Montreal since 2001.
"Being on pole here with Ferrari means something extra".
"Now he's in the spotlight, the P3 crash [in Monaco] wasn't a small error, but any small error now he is probably going to get a little bit picked apart from", he said, per Sky Sports.
When asked about the status of the component which failed in Monaco, he said: "I wouldn't describe it as serviceable.it's not happy!" Circuit Gilles Villeneuve... Gilles is huge for Ferrari and Canada is linked to that name.
But Ricciardo points to the fact that neither Mercedes driver used Pirelli's faster hypersoft tyre, the team electing to run on the harder compound instead because it has selected fewer sets of the pink-rimmed rubber than its rivals for the Canadian Grand Prix weekend.
"I don't know, I haven't seen much of the times of the others so it's hard to read yet. It's great when you have a session like that".

The ornate Edwardian building near Hyde Park opened as a hotel in 1902 and recently underwent extensive renovations. Around 120 firefighters and police officers were called to the scene, and the surrounding roads have been closed.
"I think he's pretty headstrong; he won't let it get to him too much", said the Australian, who won in Monaco and now sits in third place, 38 points behind Hamilton, in the standings.
Strategy watch: Max Verstappen will have to pit earlier than the cars around him, but he starts the race on the quicker, grippier hyper-soft tyre. It's a long race and a lot of laps, a lot of things to look out for so we will see.
When asked if he felt Red Bull had the pace for pole after seeing teammate Daniel Ricciardo go quickest in Q2, he said: "I knew we had a good vehicle, but I wanted to wait and see how competitive we would be in Q3". Maybe in the first half of the circuit a bit more.
"We are just lacking power so we try and compensate with that".
"We extracted the best we could have from qualifying", he added.
"I think so", he said with a laugh.
However, when asked a similar question during the official FIA press conference on Thursday morning, he added: "I'm getting really exhausted of all the questions".
