Inexpensive and relatively fast OnePlus 3T battery replacement service in Toronto?

Right now I'm leaning towards Ming Wireless, which said they can do it in an hour for $70. The only thing is that they're not close to me and because they're closed on weekends (and only open till 6 during the week) I would probably have to take time off work to do it, which isn't super ideal. Still, it seems like the best bet at the moment, from what I can tell. Does anyone know of anywhere cheaper, and preferably closer to the Willowdale neighbourhood if possible?
