Easter Monday is a regular day of business for many, but not for all.
London's shopping centres including Citi Plaza, White Oaks Mall, Westmount and Masonville Place will all keep regular Monday hours. It's a normal day for most other retail stores and the beer stores. Banks are also open.
Some LCBO stores are open. You can check your closest outlet HERE.
However, government offices are closed. There won't be any mail delivery or garbage pick-up. Public library branches are also closed on Monday. Kids are out of school so traffic ought to be lighter than usual.
