No it does not.

And they do list the calories to two digits (which are <5g), list sugar as the primary ingredient, and have a footnote saying that the sugar is < 0.5g.

The disadvantage of standardized labelling is that there will be edge cases, such as when the serving size is under half a gram. Some other countries standardize on 100g for size, but for tic-tacs that would be more than 3 typical containers worth. Listing all three (portion, container and 100g size) would require a fold-out label to fit, which would negatively impact a product kept in purses and pockets.
