What is gmg papa johns?

GMG stands for Grewal Management Group. They are a major Canadian franchisee. Essentially, they own and operate a large number of Papa Johns locations. You'll find their restaurants mostly in Western Canada, especially in British Columbia and Alberta. They are the local operator for those specific stores.

I am from Australia and I see this GMG Papa Johns too. It is not a new pizza. GMG is a big company that owns many things. They bought Papa Johns in Australia. So now, the Papa Johns shops here are run by GMG. It is the same pizza you know, but a different company owns it. That is all. I hope this helps you understand. It confused me too at first.
