Canada Dry is a brand of soft drinks owned since 2008 by the Texas-based Dr Pepper Snapple Group. For over a century Canada Dry has been known for its ginger ale, though the company also manufactures a number of other soft drinks and mixers. Although Canada Dry originated in its namesake country, it is now produced in many countries around the globe, including the United States, the Middle East, Europe and Japan.
The “Dry” in the brand’s name refers to not being sweet, as in a dry wine. When John J. McLaughlin, who first formulated “Canada Dry Pale Ginger Ale”, originally made his new soft drink, it was far less sweet than other ginger ales then available; as a result, he labeled it “dry”
