CTV and CBS have upped their latest orders of Flashpoint to 18 episodes after they picked up an additional five episodes for the second season.

CTV, which originally developed the Canadian cop series that made an unusual leap to U.S. network TV, was the first to increase its order, according to Avamar Entertainment’s Bill Mustos, who shares executive producer credits on Flashpoint with Anne Marie La Traverse of Pink Sky Entertainment and Tassie Cameron.

CBS Paramount Network Television, which unveiled a 13-episode second season order in mid-September, followed CTV by coming in for another five episodes two weeks ago, a Los Angeles-based spokesman for the U.S. network confirmed.

The Canadian series’ first season of 13 episodes aired on CBS in reverse simulcast, and became the network’s top original scripted series over a summer run that averaged 7.73 million viewers.

Mustos says his team always planned for 18 episodes, so the writing team has made no major adjustment for a longer second season.

At the same time, the longer 18-episode run will help amortize production costs for the second season.

Flashpoint stars Enrico Colantoni, Hugh Dillon and Amy Jo Johnson, and portrays an elite Toronto tactical police unit.

The latest series’ orders bring to 31 the number of Flashpoint episodes now being sold internationally by international distributors Alchemy Television and TeleMunchen Gruppe.
