A widowed mom, a streetwise orphan, and a gym teacher are the leading nominees for the 2015 Canadian Screen Awards, celebrating the best in film, television and digital media.

The Academy of Canadian Cinema and Television today announced their picks for the awards show, which will be held on March 1 at the Four Seasons Centre for the Performing Arts in Toronto and will air live on CBC starting at 8 p.m. ET. The awards will be hosted by Emmy Award-winning comedian Andrea Martin.

With 13 nominations, sci-fi clone series Orphan Black starring Tatiana Maslany is the top TV contender. The CBC's Mr. D starring Gerry Dee and Call Me Fitz starring Jason Priestley are next, with 10 nominations apiece. The police drama 19-2 also secured 10 nominations.

In the world of feature films, Mommy is leading the pack with 13 nominations. It stars Anne Dorval, a Quebec actress, as a widowed mom overwhelmed by the difficulty of raising a troubled, sometimes violent son. Mommy, directed by Montreal's Xavier Dolan, took home the jury prize at the 2014 Cannes Film Festival.

David Cronenberg's satirical thriller Maps to the Stars, starring Julianne Moore and Canadian actress Sarah Gadon, is also well-represented with 11 nominations. The film centres on the life of two former child stars in Hollywood, and can be seen as a cynical commentary on the entertainment industry.

There are 128 categories for film, television and digital media, with the vast majority — 97 — dedicated to TV alone.

CBC has garnered 97 nominations, which includes selections for TV drama as well as news and current affairs programming. CBC News The National has received nine nominations and the fifth estate has four. 

The Canadian Screen Awards replaced the Gemini and Genie Awards in 2013 and were hosted in 2013 and 2014 by Martin Short.
