All eight episodes of the fourth season will be available on Thursday, May 21.
Filmed in North Bay, Ontario and Manitoba, this season finds the crew disrupted like never before. The arrival of new rookie pilots and medics unsettles the dynamic as leaders begin losing control, rookies push limits, and emotions override protocol.
The drama stars Natasha Calis, Morgan Holmstrom, Mercedes Morris, Sydney Kuhne and Aaron Ashmore.
Recurring guest stars include Lauren Lee Smith, Shawn Ahmed, Leishe Meyboom, Alexander Eling and Cecilia Lee.
Julie Puckrin created the drama. She executive produces with Gillian Hormel and Vanessa Piazza. CBS Studios and Piazza Entertainment produce.
