The City of Toronto outlined a tough plan for transit, traffic and safety measures Thursday, warning residents to be patient and expect delays as huge crowds flock to downtown during of six Taylor Swift shows scheduled for next month.

Swift will perform at the Rogers Center for her sold-out Eras Tour Nov. 14-16 and the following week Nov. 21-23, and the city says it’s expecting up to 500,000 visitors from outside Toronto.

Tens of thousands of Swifties are expected to use public transit to get to the venue and the Metro Toronto Convention Centre, where the Taylgate’24 fan event is taking place, while overlapping events at Scotiabank Arena could attract up to ‘to 20,000 additional people in the city center.

City officials advise anyone planning to attend events downtown to use public transportation, bike share, walking or other alternative methods and to avoid driving.

To mitigate anticipated traffic impacts and ensure residents and visitors can travel safely and efficiently around the Rogers Center during the concert period, the city will implement the following road closures and restrictions on concert dates:

• Beginning at 1 p.m., the westbound lanes of Bremner Boulevard, between Rees Street and Navy Wharf Court, will be closed. Eastbound lanes will remain open to traffic in both directions.

• At 2 p.m., Bremner Boulevard between Spadina Avenue and Simcoe Street, Blue Jays Road between Spadina Avenue and south Front Street, and Navy Court Wharf will be reserved for residents and local businesses. Access to condos within the area will be at a police checkpoint at the intersection of Spadina Avenue and Bremner Boulevard. The Marriott hotel will be accessible from Front Street via Blue Jays Way.
• The northbound lanes of Rees Street will be closed while the southbound lanes will remain open to two-way traffic, including an accessible entry point.
• Lake Shore Boulevard will be reduced to two lanes westbound at the intersection with Rees Street for a drop-off/pick-up point.

• At 10 p.m., Front Street between Blue Jays Way and Simcoe Street, John Street south of Wellington Street and Windsor Street south of Wellington Street will be closed to allow for crowd control before spectators leave the Center Rogers.

• At 11 p.m., the eastbound and westbound Gardiner Expressway exit ramps to Spadina Avenue will be closed to restrict traffic in the area as spectators leave the Rogers Centre. Additional spot road closures may be necessary to manage crowds and traffic.

“We plan to reopen all roads by 1 a.m., once crowds and traffic have dispersed after the shows,” said Barbara Gray, general manager of Toronto Transportation Services.

City officials previously announced a limited activity zone between King, Jarvis and Bathurst streets and Queens Quay from November 14 to 23. In this area, construction, filming and utility outages will not be permitted on concert dates. Emergency work will still be permitted where necessary, and long-term construction work on the nearby Gardiner Highway will continue.

The TTC says it expects to accommodate an additional 20,000 passengers on concert days and will therefore benefit from additional service on subway lines 1 and 2 in the hours before and after Swift’s schedule. They also plan to increase the number of streetcars and buses on some routes, including the 509 Harbourfront and 510D Spadina. Acting TTC boss Gregory Percy says he’s confident he can move everyone safely and quickly.

“We looked at routes and we rerouted and we added service and we added equipment, we have people waiting and despite all the good plans you have in place, you have 10 times more emergency. plans,” Percy said. “We too will pivot at night, we will reinforce the staff each night of the concerts so that we can act quickly to accommodate.”

City officials say there will be careful crowd management at Toronto’s Union Station, with additional staff and signage to guide fans to concerts. They also suggest using other stations in and around the concert venue — like St. Andrews Station — to help alleviate the rush of people passing through Union Station.

Toronto police say they will work with event organizers and local stakeholders to manage security measures and crowds. Authorities say there will be a large and visible police presence, both inside and outside the concert hall.

“For Swifties, we strongly discourage non-ticket holders from gathering outside the venue as no fan zones will be set up and we want to keep these areas as clear as possible,” said the deputy head of police, Lauren Pogue.

Police officials add that they have consulted with forces in other countries that have already hosted the Eras Tour and that, like any large-scale event, they will constantly monitor potential threats.

In August, security concerns at Taylor Swift concerts drew attention after Austrian authorities announced they had arrested suspects and foiled a plot to attack shows in Vienna with knives or homemade explosives. The shows were canceled.

Pogue said there was “no threat at this time” and that law enforcement would continually monitor security.

City officials project that the economic impact of Taylor Swift concerts on the city will be in the order of $282 million, with visitors accounting for 93 percent of spending.
