Hi LatexinTO,
I’m guessing you’ve seen this but just in case … the Toronto list is in post #1 here.
I’m not personally familiar with the market but the most effective approach to “sort through” a cluttered or diverse market like Toronto would be to do most of your initial research on the phone to find out what each of them has available on their floor for testing that meets the criteria you are looking for so you can focus on the ones that have a wider selection that is in your budget range.
