Toronto hospital officials are preparing for an influx of patients during next month's G20 summit in the event that protestors are injured.

Non-emergency appointments at Toronto General Hospital are being rescheduled for after June 27 -- when leaders from 20 developed countries leave the city -- so that enough beds are available for a high volume of patients, CTV has learned.

At past summits, some protestors have required hospital treatment after unruly crowds were dispersed with tear gas.

Other parts of Toronto are also bracing for disruptions.

The University of Toronto downtown campus will shut down from Thursday, June 24 to Sunday, June 27 and students in residence will be temporarily moved away from the official protest site at Queen's Park.

Police are warning motorists to expect delays as leaders are ferried to and from Pearson International Airport.

Travellers are also warned to plan extra time for trips to the airport.

Flights out of the Toronto Island Airport will not be affected.
