Is Tale of Fairy Ice Trail Considered Canon?
I don't think so, I've searched Fairy Tail Wiki and found this:


  Tale of Fairy Tail: Ice Trail (氷の軌跡, アイストレイル, Aisu Toreiru) is a Japanese manga series by Yusuke Shirato and a spin-off of Hiro Mashima's manga series Fairy Tail.


If it's a spin-off I don't think it's canon
