New detective. New cases. New locations:
Slate for 4×01 – Diplomatico.

Toronto horror filmmaker David Cronenberg guest stars as a clinical psychiatrist in 4×02 -,The Scorpion and the Tortoise:

Courthouse:

All the cases are set against a backdrop of real locations in the city as Toronto becomes a character in the series just as New York City is a character in the original series and spinoffs.
Like most of the original Law & Order stories, each of our episodes is inspired by a Canadian headline (sometimes even two or three). Our goal is take a story you may already know and turn it in a different and unexpected direction from what actually happened. — Law & Order Toronto’s Taissie Cameron and other producers.
Season 3 locations:
Wintry park.

Season 2 locations:
Rogers Centre aka the SkyDome.


Season One Cases & Locations:
Law & Order Toronto premiered with what-would-be-the-show’s first victim celebrating at the Royal Canadian Yacht Club (where I occasionally crewed) on Toronto Island, with the CN Tower, Rogers Centre aka SkyDome and downtown skyline behind him.

And later with the show’s detectives and crown attorney striding past Toronto City Hall.

Season one cases were inspired by ripped from Toronto headlines like Rob Ford ‘s “Crack Mayor” scandal in 2013, when a video of the then-Mayor smoking crack cocaine went viral. Another case fictionalized former CBC host Jian Ghomeshi’s BDSM/rough sex scandal. And the season finale had Karla Homolka vibes with the accomplice to a convicted killer living a nice life with her new husband in a Toronto cul-de-sac until a neighbour discovers who she really is.
