Montreal has many unique features, but with its smooth surface, it actually contains some similarities to Sochi. Last year the winner did one stop, while the second-placed driver made two stops using all three compounds, which just goes to show the very wide variety of strategies that are possible. Finding the right set-up, with the correct aerodynamic and mechanical balance, is never easy in Montreal: this is one of the key factors to making the tyres work effectively there. It’s also important to take an open-minded approach to strategy, given the variable weather and safety cars that are historically possible.
