Toronto Police Chief Julian Fantino has issued a stern plea to the 500,000 fans expected to attend the Rolling Stones concert at the city's Downsview Park on 30 Jul.
Fantino said: "There's going to be a need for people to have patience, there's no doubt about that. People have to realize that before they come. There's no point in getting frustrated and upset because you have a couple of hours wait time to get on a subway car."
He advised fans to arrive early and be prepared to spend the night together as he reckons it will take until 5 am to clear the site – even though the Stones will leave the stage at 11pm.
Along with the usual concert contraband of alcohol and drugs, umbrellas, lawnchairs, blankets, coolers and recording equipment are also forbidden.
The concert, aimed at boosting Toronto's SARS-battered economy, will also include performances from AC/DC, Rush and Justin Timberlake.
