Both drivers were investigated by the stewards for not slowing sufficiently at Turn 3 after Bottas's Williams team-mate Pastor Maldonado had crashed near the end of Friday morning's session.
The reprimand is Red Bull driver Webber's second of the season. He also ran into trouble with the race officials for contact with Nico Rosberg in the Bahrain Grand Prix back in April.
Jenson Button was also called to the Montreal stewards for an improper pit entry, but escaped sanction on the grounds that he had been trying to get his McLaren out of the way of faster cars as a gearbox problem struck.
