Tim Hortons Travel Mug Sizes

[jason9945]

I see they have 15oz and 20oz travel mugs listed on the web site, does anyone know what size they match up with? is the 20oz a large or an xl?

I've asked the staff at a couple locations, and they look at me like I'm not speaking english.

If anyone has any insight into this it would be greatly appreciated.

I've done some sleuthing on my own, a timmies XL is 16oz. Perhaps a tiny little bit more.
