Really? I never knew that. With that in mind, I now understand why the People of the North loved Tim Horton's so much, and have vocally lamented its decline in quality.
Edit: Seems like the reason I didn't know that is because it's not true.
Mother Parkers [which is a privately held family company] is the supplier of coffee to McDonald’s Canada. Tim Hortons used to use this supplier prior to constructing its own roasting facility [in April, 2009]. McDonald’s has had a coffee supply agreement with Gavia Gourmet Coffee since 1983.
