Poire William from Switzerland, to buy in Vancouver
According to the VQA website, it's available at the following BC Liquor stores in Vancouver:
28th & Main 6
39th & Cambie 13
Alberni & Bute 14
Jericho Village 2
Kingsgate Mall 5
The numbers correspond to how many bottles they have on hand.
Bon Pere is one famous Swiss brand that does the pear-in-bottle (no idea where to find it here, though). I'd be surprised if there weren't others.
Edit: in case it helps your search, here's another brand: Morand.
i realize this isn't the exact product you OP are looking for - however, for others, they may be interested in the Okanagan version - no pear in bottle tho -
there is also a proposal on the table to open a tiny specialty distillery in Naramata ---- in the former doctor office ;)
