are the fitting rooms currently open and available at all times?

Depends on where you going, some are open and some are not.

Some are, just check with CSR as you shop in the stores! Thank you😊

Fitting room at old navy is open

The fitting rooms at Burlington and Rainbow are closed

I don't know about the regulations of all stores. I know that a month ago Dicks Sporting Goods was open in their dressing room.
