No they were a mixture of the show's history and the current DC comics history. It had a Hush story when Hush was never in the show. There were other reasons for this I can't remember of the top of my head.
So they're not canon, then? Just because Hush was never in the shows but introduced in the comics wouldn't rule them out as non-canon, but if there are other reasons I can understand that.
