Norton Stones in Toronto?

Can anybody point me in the direction as to where I can pick up some Norton stones? (specifically the 4k/8k combo) in or around the GTA?

I'd rather save on shipping costs.

Thanks a lot

For Naniwa CCK in Pacific Mall apparently has a variety of Japanese water stones

Thanks a bunch!
