Lou Thesz would make frequent appearances in Toronto as well as the major cities on the circuit, Ottawa, Hamilton, and London. The smaller towns would be more infrequent.
This ad for Barrie makes note of the fact that Thesz is getting ready for a shot at Buddy Rogers NWA crown 'next week'. The next bout between the two appears to be the one here in Toronto in Jan 1963 when Thesz won the crown.
I couldn't find the results for this night in Barrie but 3 days later at MLG Thesz fought Argentina Rocca to a double countout.
