ISO currywurst/German curry sausage in London, GTA or Niagara
Brandt's Meats in Mississauga carries the Knorr currywurst packaged mix, and some decent bratwurst to put it on. They are fairly close by for me, so I've bought this combo a few times, and haven't looked around very much beyond that.
Just make sure to invite some people over or plan to have a few meals because the Knorr mix is about $3 a package, so its a bit of a waste for one or two people.
