Hi Wormgalore!

This has been an issue of confusion since the game came out, however Kassandra's 'canon' status came from the novelization of the game and was the further supported by the Assassin's Creed: The Essential Guide and other non-fiction sources all identifying Kassandra as "The Eagle-Bearing misthios".

So bottom line, Kassandra is canon, the end.
