There have been small steps of progress over the past two races in Imola and Monaco, and both drivers are eager to get out on track and continue that development in Montreal.
The new front wing design that was introduced on George’s car last time out in the principality will be available for both drivers at the Circuit Gilles Villeneuve.
George said: “I feel comfortable with the performance beneath me. We just need to add a bit more performance.
“We need to keep chipping away, but I am confident the path we are on is the right one.”
Lewis said: “The car is continuing to improve, the biggest difference has been the ride quality and stability in the corners so we can be more committed.
“Corner balance itself is what we are trying to work on.”
“I am excited to see how the upgrade will feel this weekend.”
