tim hortons was definitely canadian at the start. however, the "canadian capitalism" claim no longer holds true in the modern day
the majority (51%) owners of restaurant brands international (the parent company of tim horton's) are the brazilian investment firm 3G capital
restaurant brands international itself was formed in a merger between tim horton's and burger king, and expanded by acquisition of popeye's
Tim Horton's is Brazilian, and is the sister company of an American burger chain and a chain that sells "Louisiana chicken"
