Perhaps they did and the problem is not the sights. Shooting left is extremely common when getting used to a new gun. Try adjusting your grip. Apply more pressure with your left hand and concentrate on straight back trigger pull with your right. Do not increase the pressure with your right as you increase pressure with your left. I’m assuming you’re right handed.Two things come to mind.
One...the Warner Tactical sights were a 'highlight' in the promotional ad for the Canik. It draws you in.
Two...One would have assumed all Canik's pistols would have test fired for QC purposes...although not a test pattern to ensure accuracy.
I do not believe that sight has any lateral movement...as least I don't think it does....you say?
I would try this or have an experienced shooter try the gun and see if they get the same results, before you mess with the aights. It’s rare but occasionally sights are off, but more often than not it’s the shooter.
