The two I intended to get were:
Duchesse De Bourgogne (17B)
and
Cantillon Gueuze (17E)
There are a number of Cantillon offerings and they may seem pricy but are worth it.
Both are available at Willow Park. I wouldn't be surprised if the Dalhousie Co-Op and Enoteca have them too.
Keep an eye out for Liefman's Goudenband, Liefman's Odnar or Liefman's Oud Bruin (17C). There are a number of fruit lambics available too.
Infomation on the various styles is available here, including commercial examples.
Happy tasting!
