I can't tell you how many times we've been asked where to buy alcohol in Niagara Falls, Ontario. You cannot purchase alcohol of any kind at any grocery store or convenience store. You must purchase it at The Beer Store or the LCBO (Liquor Control Board of Ontario).
There is an LCBO at 5389 Ferry Street, just up from Clifton Hill. At this location you can buy beer, wine or any other type of alcohol. The Beer Store carries mainly beer only.
