The organisers of the Canadian Grand Prix have taken the decision to cancel its open doors day due to the threat of protests from student groups.
The day allows fans to walk the pitlane and view the cars on Thursday while the teams make their final preparations for Friday practice.
However, with the mounting threat of protests by students campaigning against tuition fee increases, the organisers are worried they may use the free entry day to exercise their message.
A statement from the organisers read: “Following a serious examination of the situation, made necessary by public disruption threats and the difficulty to measure their precise validity, the organisers came to the conclusion that it is necessary to restrain the access to Circuit Gilles-Villeneuve and precisely the F1 pitlane, on the day preceding the first sessions on track.”
