What is Canadian-style sour cream?

I recently bought a container of what was labeled "Canadian-style sour cream" at a produce market in the Bay Area. Being from Canada, I was curious to see what it was, since all the sour cream I've had in Canada was the same as the sour cream I've had in the US.

But when I opened the container, it sure seemed to be regular sour cream. So what's the difference?
