Shipping in Canada is pretty cheap and all their merchandise is authentic...bought a pink dolphin tank and snapback and they were legit.
Not online but Top of the World is a skate shop on Rideau st. And there's Reap & Sew on Dalhousie. They're both within a few minutes walk to NRML and the Rideau Centre.
