I didn't know Privilege has the Valrhona Pearls. Last time I tried them (years ago) they seemed to be the callebaut ones. I buy the Callebaut pearls at Aubut. Chocolat-chocolat sells the shimmery powder that can be used to color them. For Valrhona Pearls, I would ask Vrac du Marche (at the Atwater market, I think I have seen them there before). If they don't have and won't order pearls for you, I suggest looking at the Valrhona online shop:
Edited: Just realized the above website does not ship to Canada even though their homepage says this is the US AND Canada site.
It seems you can order them at Farinex (pick up at their location) or Lentia.
Actually it's only written Chocolate Pearls on the package so yeah it could be from Callebaut, but anyway, they just sell it in small boxes.
Thanks for Vrac du Marché, I forgot about them. I'll try this week before Aubut. Better for me without a car.
As for the website, I already tried, they do not ship to Canada.
Euro Excellence imports and distributes Valrhona chocolates in Quebec. They are located in Candiac. Not sure if they are open to the public but if not will surely be able to lead you in the right direction. Here is their website: http://www.euro-excellence.org/
Hope this helps.
