According to the International Alliance of Theatrical Stage Employees’ list of productions, Good Sam started filming on Oct. 18, 2021 and was slated to be completed on March 22, 2022. The production’s address was listed as being in Oakville, Ontario, so it’s pretty likely that Good Sam filmed in Canada.

But according to Ontario's "hyper local" news outlet, Insauga, people reported sightings of Good Sam's production since as early as February 2021. Twitter user @brotherneil tweeted, “@TOFilming_EM new project has begun on @UTM campus.”

The user also accompanied the tweet with pictures from the production, one of which is a sign that clearly reads “Good Sam Crew Pay Park and Shuttle.” That would be proof enough for some people, but he also posted an image of the entrance sign to the fictional Lakeshore Sentinel Hospital being assembled before it was mounted to the building.

From the tweets, it appears that Good Sam was being filmed in Mississauga, which is a pretty popular filming location for TV shows. HBO’s Station Eleven, Freeform’s Shadowhunters, and BBC America’s Orphan Black are only some of many popular shows that have used the city as a backdrop.
