Apparently invented in 1969 by Walter Chell, the restaurant manager of the Calgary Inn in Calgary, Alberta, Canada. This drink is essentially a Bloody Mary that uses Clamato juice instead of Tomato juice. He spent three months perfecting the drink, ending up with a simple 1-2-3-4 recipe; 1 shot vodka, 2 dashes hot sauce, three dashes of salt and pepper, and four dashes of Worcestershire sauce, topped off with 4 to 6 ounces of Clamato juice, and served with ice in a glass rimmed with celery salt.

The Caesar is very popular across Canada, once it was even attempted to make it the nations official drink.
