The crooner recently withdrew from hosting the Juno Awards -- Canada's GRAMMYs equivalent -- next month to continue to care for his 3-year-old son, Noah, who was diagnosed with cancer last year.
Canadian comedian Russell Peters and Ontario-born pop singer Bryan Adams have signed on to take over hosting duties for the "I Believe in You" singer. In January, Buble withdrew from hosting the BRIT Awards in London.
Bell Media, the network broadcasting the upcoming Juno Awards, shared their support for Buble's decision and best wishes for his family in a statement released to the press on Thursday.
"Our thoughts continue to be with Michael," shared Michael Cosentino, Bell Media's senior VP of content and programming. "We respect his ongoing commitment to his family and look forward to working with him again in the future."
Buble and his wife, Luisana Lopilato announced the news of their son's diagnosis in a Facebook post in November.
"We are devastated about the recent cancer diagnosis of our oldest son Noah who is currently undergoing treatment in the U.S.," the couple shared. "We have always been very vocal about the importance of family and the love we have for our children."
In February, the couple shared a positive update about their son's fight, revealing that Noah has "been progressing well during his treatment."
"The doctors are very optimistic about the future for our little boy," they shared in statement." He has been brave throughout and we continue to be inspired by his courage." Watch the video below to hear more.
