Tim’s does bake its stuff in-store, I think. It’s just that it used to be made from scratch - and now it is analogous to the partially baked frozen breads sold or finished at grocery stores.
They are still better than competing chains for breakfast and donuts, especially in small towns (outside of Quebec). Their other meals and coffee quality might be a matter of taste. Canadians still speak highly of Tim’s, less than before, but these do not tend to be the most urbane and globetrotting segment. Still, Canada is a big place and on long drives it remains a welcome sight. It’s dependably fairly good.
