Are you sure it's the SAME kind (same winery/region/grape/vintage) of icewine? Icewines are primarly made with 2 grapes: Vidal and Riesling. Some wineries also make Carbernet Franc and Pinot Gris icewines. Vidal is a French grape and Riesling is German, they have similar but different taste.
Andrew Peller's Signature Series carry some of the best Riesling icewines in the region. Inniskillin is perhaps one of the most prestigious producers of Canadian icewine, it had won numerous awards in this category. It also carries a sparkling icewine which is a favorite appetizer wine for many people. Wine Rack sometimes sell really cheap icewine for like $16.99.
