Scarborough Arena or Scarboro as known back then was a familiar spot for Wildman shows from the early 70's up to the mid 80's as well as Universal Wrestling for a short spell in 1975. This is the earliest I can find for a show by Tunney after a 'scheduling' issue at MLG and was likely East York Arena, the usual 'go to' was unavailable also.
