eh, ok, if that's the correct term, sure. From that merriam webster link --
a schedule of duties imposed by a government on imported or in some countries exported goods
And to highlight that Canada does use export tariff verbiage, you can look at this govt site for global affairs, where they have a resource called the Canada tariff finder, which they describe as allowing you to "Look up import and export tariff rates"
But either way, you got the point.
