well of what I have understood of the canadian requirments, they are for general european ~1,000 OPV (small frigate/large corvette desing-layout fitted for secondary duty patrol). The korean boats are coastal patrol crafts with relatively shallow draugth and have small dimenssions for needed endurance in canadian long coastline.
Also, the norther waters are hars and rough, so any ship operating in ther needs to have lot more freeboard (like all Canadian ship usually have)
As for the AAA, the desing certainly has strech enough for CIWS or small BARAK/Umokhoto/Mistral level SAM for export markets, but in SK own requirments doesent need them nesserically, but then again, its never bad decission to anticipate future and sudden changes in the thread scenarios. Succesfull ship classes are always known from flexibility to have their capacities severally upgraded by installing new weapons or replacing some of the old.
