Carly Rae Jepsen cleans up at 2012 MMVAs

Giant Toronto street party drew TV performances from Nelly Furtado, Hedley, Justin Bieber, LMFAO and Katy Perry that aired live on MuchMusic in Canada and Fuse in the U.S.

The giant block party that is the MuchMusic Video Awards was held Sunday night at the corner of Queen and John in downtown Toronto, and Carly Rae Jepsen (pictured) was the big winner with three trophies.

Jepsen, who has signed with Justin Bieber and manager Scooter Braun, picked up MMVAs for video of the year,’s most watched video, and the audience-voted UR fave video of the year for her breakout hit “Call Me Maybe.”

Despite the presence of big-name international acts like Kelly Clarkson, Katy Perry, co-hosts LMFAO and Flo Rida, Jepsen and fellow Canadians came up big as winners in the juried music video competition. It also featured Nelly Furtado and Hedley.

Vancouver rockers Marianas Trench grabbed MMVAs for pop video of the year and cinematography of the year, while Bieber earned awards for international video of the year by a Canadian and the UR fave artist or group.

And the Saskatoon band The Sheepdogs won for rock video of the year for “I Don’t Know,” while the hip hop video of the year went to Drake, formerly of the Degrassi TV series, for “The Motto.”

Elsewhere in the production suite, Danny Fernades was named director of the year, while Down With Webster won for post production of the year for “Big Wheels.”

On the international front, Katy Perry took home two MMVAs for international video of the year and UR fave international artist or group, while party-rockers LMFAO grabbed the MMVA for international video of the year.

The awards show was aired live on the parent station as well as on Fuse in the U.S. Last week 4Music, a music channel in the U.K., acquired the UK broadcast rights. The show is to air at a later date.
