In a sense, the canards will provide some vertical stabilization at very high angles of attack, proving some roll stability ??? [sm=confused.gif]
What do you mean by "vertical stabilization"?
You need yaw, roll, and pitch stability. Only one of those is much affected by canards, unless there is large dihedral or anhedral to them, and then they provide some yaw instability because they're in front, not aft.
