Lewis Hamilton has insisted there are "not too many" unknowns ahead of the Canadian Grand Prix despite a lack of dry running in practice leaving strategies in the dark.
FP1 saw only five minutes of running before safety issues caused by a CCTV problem prevented any further action.
Teams were afforded an extra 30 minutes for FP2, with Mercedes completing its long runs early in the session, a strategy that contrasted its rivals.
Two red flag periods and rain at the end of the session further reduced track time, before Saturday's proceedings were exclusively wet.
Asked if there were any unknowns ahead of the race, Hamilton told media, including RacingNews365.com: "Not too many.
"We had a long run [on Friday], but it was at the beginning of the session and the track was much slower.
"The others did their long runs 45 minutes later or something like that. We will wait and see how it goes."

Hamilton sets out race target
Mercedes had struggled in final practice with Hamilton and teammate George Russell suffering from a lack of tyre warm-up on the Intermediate tyres.
But the duo will start third and fourth after overcoming the issues in qualifying and having enjoyed a promotion following a grid penalty for Haas' Nico Hulkenberg.
"[I'm] really grateful that we are on the second row," said Hamilton.
"The team has done a great job this weekend to put us there.
"Hopefully our race is stronger than the pace we showed [in qualifying], so fighting the top two drivers, Alonso and Max, hopefully, we can put on some pressure."
