TORONTO — Tragically Hip guitarist Rob Baker is urging fans to be vigilant when buying merchandise that claims to be linked to Gord Downie’s charity.

The musician tweeted Tuesday that some online shoppers are being duped into buying T-shirts, hoodies and other items that purport to donate $10 of the proceeds to the Gord Downie Fund for Brain Cancer Research.

Baker says the operators — who are using Facebook and Instagram to amplify their message — aren’t linked to the band.

One such group is “Gord Downie Supporters” on Facebook, which appears in advertisements on some user’s news feeds.

“Wear this t-shirt, and give your support!” some of the posts say.

Each link redirects to “The Hip Store,” a website that’s not associated with the band but uses a similar domain name.

From there, shoppers can browse a selection of seemingly official merchandise with images from “Secret Path,” lyrics from Hip songs and a variation of Downie’s famous “Jaws” shirt from last summer’s tour.
