First of all, Frozen Fever is not canon on OUAT ^^

Then, it is not that easier. What they really said is that events are canon, but not necessarily how they happened in the films. Like, Elsa did run away from Arendelle to build an ice castle in the mountains. But did she create Olaf? Not likely, as he does not seem to exist on OUAT.

Some events were changed too. Like the mother's real name. Gerda is not Elsa and Anna's mom in Frozen but their handmaiden. Hans' bros do not help him at all in the film, but in OUAT they do.

Same thing for Brave. The lords are not going against Merida at all in the film, but on OUAT they do.

To make it easier, the main events of the film plots are canon, but these events may or may not have happened exactly how they are depicted in the film.

That's why we decided to only add mentioned events on the pages, to be sure to stay consistent with how OUAT is depicting the films events :)
