Both drivers were pleased with the car balance after a productive day of running, but the pecking order is tough to gauge because they have yet to sample the HyperSoft tyre in Canada.
"Overall we've had a fairly straightforward day, the car has run reliably and it was just the red flags and virtual safety cars that caused us to have to adapt the plan a little," explained Trackside Engineering Director, Andrew Shovlin.
"The car balance has been good from the first run so it has just been a case of small balance tuning to keep the car in the right window as the track grip came up.
"It's difficult to judge our single lap pace from today as we haven't run the HyperSoft and some of our closest competition looked to have had less than perfect sessions.
"However, comparing on the same tyres, we do look to be in better shape than we were in Monaco.
"The long runs seem consistent, with the tyres behaving normally although as always, Ferrari and Red Bull look to be very similar pace and we'll need to wait until Sunday to see how we actually stack up."
