Ontario’s LCBO Has Nation Based Beer Quota?

Interesting comment on Ontario’s LCBO, the province’s sole wholesale import beer buyer. The comment is from an Estonian supplier newly selling its beer into this my local marketplace:

In an April 11 statement, A. Le Coq said its product should arrive on store shelves in the province’s major cities this week. The brewery’s director Tarmo Noop said that entering the Canadian market was a long and difficult process. “In Canada the government puts very strict controls on alcohol sales and in connection with that, very tough regulations are in effect for both importers and imported goods,” he said. As an example, Noop said that only one brand of Estonian beer could be sold on the market at one time. The company also had to redesign its packaging to meet local regulations.

Really? Is this just for Estonia or do all nations have to send us only a few of their brews? How many German, French or Italian beers can be on the shelf at one time? Where is the chart of these national quota levels and who came up with it?
