ABC just gave a big show of support to its summer cop series: The network picked up Rookie Blue for a third season. In fact, season three is already in development and will shoot in Toronto later this summer.

The drama ranks No. 1 in its Thursday at 10 slot among adults 18-49. ABC says Rookie Blue is producing year-to-year gains, improving by 8% in total viewers and by 14% in adults 18-49 versus the network’s averages in the hour last summer.

Rookie Blue follows five ambitious rookie cops and stars Missy Peregrym, Gregory Smith, Charlotte Sullivan and Enuka Okuma.
