A small stretch of Queen Street will be shut down tonight as Hudson’s Bay unveils its holiday windows at the Eaton Centre.

The HBC window reveal is expected to feature fireworks, as well as a performance by singer Mariah Carey, whose 1994 Christmas recordings have become ubiquitous during the holiday season.

Queen Street will be closed between Yonge and Bay streets from 5:30 to 8 p.m. to accommodate the event.

During the closure, 501 Queen streetcars will be diverting both ways along Shaw, King and Church streets.

The TTC says that 501 and 503 shuttle buses running along the route due to an existing diversion will be diverting as well.

Eastbound buses will travel east on King Street, south on Strachan Avenue, west on Douro Street, north on Shaw Street, east on Queen Street, south on University Avenue, west on Adelaide Street, north on Church Street, east on Queen Street to Jarvis Street.

Westbound buses will run south on Jarvis Street, west on King Street, north on York Street, west on Queen Street and south on Shaw Street.

Presto card readers may not be available on those buses, the TTC says.
