Cake Help!

This is a very niche, very specific type of request that I completely understand if everybody ignores.

I LOVE fortinos cake. I live off of it, and I eat literal whole cakes throughout the week from Fortinos (I used to live in Brampton). Fortinos has a very specific type of frosting, it's heavy and gluttonus and de-fucking-licious. I tried a cake from Sobey's and the frosting was too light for my tastes.

Is there anywhere in the Kitchener, Cambridge, Guelph area where I can get a cake with that type of frosting?
