The high speed nature of Montreal's Circuit Gilles Villeneuve puts the emphasis on power, medium downforce and top speed.
As usual, the speed trap reading offer some useful insight into who has part of the right ingredients to produce good pace around the 4.4km layout.
Charles Leclerc's Ferrari-powered Sauber clocked in with the fastest top speed on the track's back straight, with 329.3 km/h.
The performance however outdid that of his team mate Marcus Ericsson by almost 9km/h, reflecting contrasting setting between the two drivers' car.
Unsurprisingly, as regular contenders for the fastest top speed, Force India's drivers were next in line in their pink VJM11.
The tail end of the field offered another habitual stat, with McLaren's MCL33 once again among the slowest cars in terms of straight-line speed, despite theoretically benefiting from a new-spec and more powerful Renault engine.
However, Mercedes' Lewis Hamilton and both Red Bull drivers were also in the third tier of the ranking, underlining perhaps a set-up balanced more towards handling - and tyre management - than top speed.
