So... Shadow of the Queen, yes. Adam Horowitz said it was canon, so we should count it and even put it in the summaries.

For the specials, no. They are specials episodes, there is no new archive footage, there is no new information. This is just a big recap of the season. Nothing new, nothing more than the eps we saw. A example: at the beginning of each episode, we have the "Previously on Once Upon a Time" which is a recap of some previous events. So, it is like the specials ep: recapping what happened, with no new info. Now, if we watching the onf from "The Miller"s Daughter", there is some recapped events as Hook attacking Rumple. So he appeared in this part, but not in the ep. If you read Hook's page, you'll see we do not count him as present in the 216.

So, because they're like this section ("Previously on"), I think we should not count the specials eps. Because, they bring nothing new in the series :)
