TORONTO -- The stars have arrived at the Canadian Screen Awards.

Homegrown celebs including film director Atom Egoyan, "The Amazing Race Canada" host Jon Montgomery, "Rookie Blue" actress Missy Peregrym and "Heartland" star Amber Marshall were among the early arrivals at the annual bash celebrating the best in film, TV and digital media.

Marshall, one of the night's presenters, says she loves the energy on the red carpet and the feeling of camaraderie it brings.

The sci-fi clone saga "Orphan Black" and Xavier Dolan's acclaimed film "Mommy" are the ones to beat.

The Space series "Orphan Black" is up for best TV drama and best TV drama actress for star Tatiana Maslany after already having collected eight trophies at a previous non-televised gala.

And Dolan's "Mommy" will compete in the top film categories including best film, best director and best screenplay after claiming the best foreign film title at France's Cesar Awards and the prestigious Jury Prize at the Cannes Film Festival last year.

Comedy star Andrea Martin hosts the bash, which celebrates the best in film, television and digital media.

"Orphan Black" and "Mommy" lead the nominees with 13 apiece.

Other big contenders include David Cronenberg's dark comic film "Maps to the Stars," with 11 nominations, including a best actress nomination for U.S. star Julianne Moore.

Fresh off her Oscar win for "Still Alice," Moore is expected to be among the presenters, as are homegrown celebs Maslany, Bruce Greenwood, Eugene Levy and Kiefer Sutherland.

"Maps to the Stars" faces off against "Mommy" in the best film category, along with "Cast No Shadow," "Fall," "In Her Place," and "Tu dors Nicole."

Maslany seeks the best actress trophy for her turn as several cloned characters on the smash Space serial. Meanwhile, "Orphan Black" competes for best dramatic series against Bravo's "19-2," Showcase's "Continuum," CTV's "Motive," and Global's "Remedy."

The best comedy race pits CBC-TV's "Mr. D" against TMN/Movie Central's "Call Me Fitz," City's "Seed," CTV's "Spun Out," and Super Channel's "Tiny Plastic Men."

Marshall said she enjoys the chance to see everyone celebrate together.

"I absolutely love the energy on the red carpet," Marshall said Sunday.

"It's this whole form of cameraderie that we're all here together and we're all enjoying this. And I absolutely love that."
