Hi LJsleep.
Welcome to our Mattress Forum! 
Subject to first confirming that any retailer or manufacturer on the list that you wish to visit is completely transparent (see this article ) and to making sure that any mattress you are considering meets your criteria and the quality/value guidelines here … the better options or possibilities I’m aware of in and around the Toronto, ON area are listed in post #1 here which has some listings and suggestions I used to offer for this area, however, I have decided to discontinue the provision of listings of potential retailers in various geographic regions (unless they are already Trusted Members of our site), because of the difficulty in maintaining such listings in a retail landscape that is constantly changing, and most importantly the confusion it was creating with the consumer members who incorrectly assumed that these businesses had gone through the strict qualification process and were approved as members of The Mattress Underground.
