They do, but I imagine there are quite a few (all?) cake shops that would refuse to make cakes with particular messages. What if, for example, a gay owned bakery was asked by a Muslim Imam to make a cake with the message "Thank Allah for the Pulse nightclub shooting"? Would the bakery be in violation of the CRA as they are discriminating on the basis of religion? The question in this case was not whether the baker would sell a cake to a gay person (he was willing to do so), it was whether the baker had to make a cake with a particular message that he felt violated his personal and deeply held beliefs.
