01 Championship · Antonelli 100 / Russell 80 / Leclerc 59
Mercedes lead a championship after four rounds for the first time since 2021.
Antonelli has converted every front-row start into a win or a podium. Russell has out-qualified him only once. The Mercedes story this weekend is whether either driver wants to play the long game.
02 Mercedes · home advantage
Russell goes to Montreal as defending winner, leading his team-mate in the season opener since.
Mercedes have brought their first significant upgrade of the year. The factory mood is that Montreal is where the car was designed to be quick. The pressure on Russell to deliver in front of his own home of motorsport is not trivial.
03 Ferrari · weather
Leclerc's Saturday in Saudi was the standout drive of his season. Sunday rain is forecast.
Ferrari are quietly the second-best wet-weather car of 2026 so far. A wet race opens the only realistic path to a Leclerc win this weekend. Whether the front rolls in is forecast 42% as of Tuesday.
04 McLaren · intra-team gap
Norris and Piastri are eight points apart, but the qualifying gap is two-tenths a session.
Norris has the points, Piastri has the pace. The team's race-day calls have favoured Norris on three of four weekends. Montreal is the first circuit where Piastri's strengths (low-speed braking, kerb riding) should dominate.
05 Red Bull · slow start
Verstappen sits seventh in the championship. The last time he was this low after four rounds was 2017.
The RB22's narrow tyre window has cost Red Bull positions on every Saturday and again on every Sunday. Montreal's traction zones are not a strength of this car. Red Bull need a track they hate to find what is actually wrong.
