Key Canadian nominees include Sandra Oh, Samantha Bee, Eugene Levy and Catherine O'Hara

At the 71st Primetime Emmy Awards Sunday, several notable Canadian actors and productions will get their shots. CBC TV comedy Schitt's Creek, co-created by Dan Levy, left, and his father, Eugene Levy, is a lead contender for best comedy. Killing Eve star Sandra Oh, right, earned her second consecutive nomination for lead actress in a drama.

Many of the biggest stars in television and streaming entertainment gather tonight in Los Angeles for the Emmy Awards, the U.S. Television Academy’s annual celebration of excellence.

Here are four storylines to keep track of as the awards get underway:

No host

Following in the award-show footsteps of the Oscars and the Canadian Screen Awards, the Emmys have nixed the notion of a traditional emcee (or two).

Instead, a cavalcade of famous presenters will be expected to keep the show moving. Lilly Singh, Viola Davis, Michael Douglas, RuPaul, Amy Poehler and the casts of Game of Thrones, Veep and Keeping Up with the Kardashians are just a taste of who’s on the bill.

No host likely means the evening will be light on sketches, although we’re not complaining. One of last year’s most delightful moments was impromptu and totally unplanned (by organizers, anyway): the surprise on-stage marriage proposal Oscars director Glenn Weiss, winner of best direction of a variety special, made to his girlfriend, Jan Svendsen.
