The 'I Believe in You' singer has dropped out of fronting the ceremony in Canada next month in order to focus on caring for his three-year-old son Noah, who has been receiving treatment for liver cancer.

Instead comedian Russell Peters will again take the reins for the ceremony alongside 'Run to You' hitmaker Bryan Adams, who has an impressive 18 Juno wins to his name.

Russell said in a statement: "Third time's a charm! And who better to share the stage with than Bryan Adams?! I'm actually really excited to be back, and looking so forward to making the 2017 Juno Awards a memorable one."

Bryan added: "I'm honoured to be co-hosting this year's Juno Awards alongside Russell Peters. We have an incredible music community in Canada and this is the night we celebrate its success."

Michael, 41, previously stepped down as host of the BRIT Awards, which took place last month, and also pulled out of performing at the BBC Music Awards in December following Noah's diagnosis.

At the BRITs last month, replacement hosts Dermot O'Leary and Emma Willis suggested the crooner - who also has son Elias, 13 months, with wife Luisana Lopilato - could host the 2018 ceremony instead.

Dermot said: "While Emma and I are so happy to be your hosts, we would much rather be down there in the audience, watching Michael Buble up here."

And Emma added: "We so wish he could have been with us this evening and everyone here at the BRITs send our love and fingers crossed he will be here next year."

The Junos take place on April 2 in Ottawa and will feature performances by Alessia Cara, Shawn Mendes, and Sarah McLachlan.
