What about Lay's and Pepsi is 100% Canadian?

When I think of things that are 100% Canadian, Lay's and Pepsi are not at the top of my list.

Lay's was founded in 1932 in Ohio, and has been part of Pepsi since 1965. The Pepsi name has been in use since 1898, and the Pepsi Cola company has existed since 1902. Founded in North Carolina, Pepsi is currently headquartered in Purchase, New York.

So, what about products from two American companies is 100% Canadian? I'm sure that the potato chips and cola are manufactured in Canada, but the brands are American. For me that fails the 100% Canadian test.
