Why are they?
The Canadian Levis stores don't carry any of the raw denims except the LVC ones. Theres a store on Yorkville called Over the Rainbow that sells the raw 501's, but they're like $75. If you want the raw ones i suggest you order them from Sears or the Levis website.
I buy shit from The Bay, they have some really nice Tommy Hilfiger and Ralph Lauren shit.
Toronto, if you go to any Bay downtown you'll see Ralph Lauren.
