"Mayor of Kingstown," while set in the state of Michigan, is shot in the city of Toronto in Canada (via Decider), one of the most popular cities for North American filming productions. Toronto is located in the province of Ontario, though, which shares a border with the state of Michigan — with Toronto only being a 4-hour drive from Detroit (per Trippy).
However, the show shooting in Ontario has more significance than simply being close to Michigan. Hugh Dillon, who co-created the show alongside Taylor Sheridan (and plays Sheriff Donnie Haskell on "Yellowstone"), hails from Kingston, Ontario, the town that the fictional Kingstown is based on (via Men's Health). The real-life town of Kingston has nine prisons, though the fictional Kingstown has seven (via The Kingston Herald). Kingston is roughly a three-hour drive from Toronto, according to Trippy.
"Mayor of Kingstown" just finished Season 1, and is available to stream on Paramount+.
