Another Syfy series is shooting in Canada, the space-based thriller Ascension, a six-hour event series that has started the cameras rolling in Montreal.

The U.S. sci-fi channel has already picked up a slew of Canadian-made series like Bitten, Haven, Lost Girl and Continuum for stateside broadcast.

Syfy is also coproducing with Space the adventure drama series Killjoys from Temple Street Productions, which offers an exclusive stateside debut of a sci-fi series for a modest license fee.

And the U.S. channel has shot-in-Canada American series like Defiance, which was shot in Toronto, the cancelled Warehouse 13 series, and now Ascension in Montreal.

Ascension, which gets Syfy back into the mini-series business, is a thriller about a murder aboard a space shuttle on a century-long journey from Earth.

The event series, to debut in November 2014 and air through December, stars Brandon P. Bell, Brian Van Holt and Battlestar Galactica‘s Tricia Helfer.

While only six hours in length, Ascension could still become a potential series if it performs well with audiences at the end of the year.

The ensemble cast includes Tiffany Lonsdale, Andrea Roth, Jacqueline Byers, P.J. Boudousque and Ryan Robbins.

The event series is produced by Lionsgate Television and Sea To Sky Studios, in association with Jason Blum’s Blumhouse Productions.

Universal Cable Productions and Lionsgate Television are co-financing and handling distribution on the series.

Ascension is executive produced by Blum, creator and showrunner Philip Levens, and Ivan Fecan, Tim Gamble and Brett Burlock for Sea To Sky Studios.
