This show just started airing on the Retro TV channel in the US. I vaguely remember this as a child, airing on a local TV station on Saturday afternoons. Looking at it now, as a adult, I'm in a constant state of wincing and cringing! In comparison to EMS icon "Emergency," which spurred many of my generation to enter the world of firefighting and the burgeoning pre-hospital care service, it looks like this dreck was foisted upon many poor souls in that "Metro" city with the big tower (what, were Canadians THAT embarrassed by the show to associate it with "Toronto?")
Even worse, the show originally started as "Dr. Simon Locke," a Canadian version of Marcus Welby (the producers' pedigree did include involvement in an earlier medical procedural, Ben Casey), but quickly collapsed due to poor production standards (well-respected star actor Jack Albertson walked off the show and laughed off breach-of-contract threats, using the show as his own defense!)
If this show pops up ion one of your syndicated or "classic" TV stations, here's an all-points bulletin: avoid it at all costs!
