Calling off first practice at the Canadian Grand Prix was "embarrassing" for Formula 1, according to Fernando Alonso.
Fans turned out in their thousands to get their first glimpse of F1 cars on track on Friday. But they only got about five minutes' worth of that in FP1 before the Circuit Gilles Villeneuve was quiet again.
The red flags were brought out by Pierre Gasly, who suffered a mechanical problem. But what was expected to be a brief stoppage eventually turned out to be the end of the session.
