Crooner Michael Buble came out on top at the Junos Sunday night, taking four awards including album of the year for "Crazy Love." Toronto hip-hop artists Drake and K'naan were the other big winners, taking home two trophies each.

Buble opened the broadcast by serenading fans with his hit single, "Haven't Met You Yet," walking through the crowd and shaking hands with audience members as he sang.

With Pop Album of the Year awarded to him the previous night, Buble cleaned up with three more awards during the Sunday show, including Juno Fan Choice Award and Album of the Year.

He seemed especially pleased with the Fan Choice Award.

"This is the best one," Buble said from the stage. "I mean, because we talk about our managers and our companies and all that stuff but we don't talk about you enough. The fans, without you, none of this happens."

Buble also took home Single of the Year.

"I would like to thank Canadian radio for playing the heck out of this thing and all of you for listening to it," he said, admitting to being nervous.

Buble concluded the evening by receiving Album of the Year. "Thank you very much for making this a huge night for me, I love ya."

Meanwhile, K'Naan joined the esteemed company of Leonard Cohen, Bryan Adams and Feist as he was presented Songwriter of the Year for "Waving Flag."

"It's a real honour and a real pleasure," the Somali-born Canadian said, holding his crystal award. "There is no greater dream than the one that comes true in the way of the song," he said. "I really appreciate you, Canada."

On Saturday evening, he was also presented with the Artist of the Year award.

The highlight of the evening was a performance of K'naan's Juno-winning song. He began the final performance of the night by singing the iconic song alone at the piano, only to be joined by an all-star Canadian chorus including Drake, Nikki Yanofsky and Justin Bieber.

Humanitarian award

Earlier in the evening, K'Naan celebrated Bryan Adams's lifelong commitment to humanitarian work. Adams helped organize the Northern Lights project in 1985 that raised money for African famine relief. He also donated his studio for recording the recent Young Artists for Haiti video, a project committed to raising funds for those still in dire need in Haiti.

"We are the free helping the un-free," Adams said, in a recorded message. "It's part of my nature to want to do things like this."

Adams graciously accepted the award from London, where he was stranded because of Iceland's volcano ash, crediting those who constantly give "to other people with needs greater than their own."

Although Bieber came up short in the three categories he was nominated in, host Leah Miller was nearly drowned out by screaming fans as she announced teen dream's performance.

Bieber had fans singing along to his song, "Baby" and the crowd grew to be near deafening as Drake rapped with him on stage.

Legendary rockers April Wine were also inducted into the Canadian Music Hall of Fame during the ceremonies. Lead vocalist Miles Goodwyn thanked their fans for "their love, their respect and their unwavering support."

The party continued throughout the awards ceremonies on George Street as fans celebrated with Newfoundland's Premier Danny Williams and Olympic gold medalist, Jon Montgomery.

Not only Montgomery the fastest man on a skeleton sled, he also has fast-flying auctioneer's lips, and joked about taking bids for Justin Bieber's phone number and Jim Cuddy's room key.

Inside the building, musicians were introduced by a stellar roster of Canadian talent including Dallas Green, LIGHTS, Jully Black and Shiloh.

Rockband Stereos named Metric as Group of the Year.

"This has been an unbelievable year," said Metric's lead guitarist James Shaw.

The band also won the Juno for Alternative Album of the Year for their record, "Fantasies."

Performance of the night

Against the backdrop of icebergs, country singer, Johnny Reid, rockers Billy Talent, roots musicians Great Lake Swimmers, indie rockers Metric, iconic Canadian rockers, Blue Rodeo and rapper, Drake performed for the Newfoundland crowd.

Though he has yet to release his first full album, Drake collected both Rap Recording of the Year and New Artist of the Year.

The former Degrassi star turned rapper beat out teen heartthrob Justin Bieber but graciously hugged him before accepting his first award.

He dedicated the award to his mother.

"She's responsible for not only the artist that I am, but the man that I am," Drake said.

"Justin Bieber, you work really hard, man, and I want to share this with you," he added.

When he won for Rap Recording of the Year for "So Far Gone," he beamed on stage: "This is two."

East Coast rapper and Juno-nominee Classified kicked off the broadcast, performing his hip-hop version of "Oh Canada" on George Street, amid a giant street party. "Oh Canada, we love our Bieber," he said, changing many of the lyrics to include nominees.
