Pirelli has confirmed which tyres each driver will have available to them during the Canadian Grand Prix in a fortnight, with the majority favouring the ultrasoft compound.
The leading teams have all converged on similar strategies, with Mercedes opting for eight sets of the ultrasoft for both Lewis Hamilton and Nico Rosberg, two of the supersoft and three of the soft compounds.
Ferrari, Williams and Red Bull have chosen seven sets of the ultrasoft each, though they differ on their allocation of supersofts and softs, with Red Bull opting for an additional set of the more durable yellow soft tyre.
Valtteri Bottas and Felipe Massa are the only team-mates to have chosen slightly different strategies, with the former electing for just two sets of the soft and one more of the supersoft.
Renault and Haas have gone for an aggressive strategy which sees both teams completely ignore the supersoft in favour of additional sets of the soft for Renault (5) and ultrasofts for Haas (10).
The Circuit Gilles Villeneuve isn't aggressive on tyres, hence the same line-up as Monaco, with one stops likely, though some drivers may opt for two if it proves quicker.
