Mann passed away following a battle against early onset Alzheimer's disease. He revealed his diagnosis in 2014, more than a year after learning of it himself.
Spirit of the West performed their final shows in April 2016.
So far, messages of condolence have been shared by everyone from musicians to radio personalities to health organizations to theatre companies to Prime Minister Justin Trudeau — proving just how big and wide-reaching Mann's impact was on Canada.
Mann has even received tributes from across-the-pond admirers, including Billy Bragg.
See some of the tributes below.

I'm knackered again, come on sleep take me soon."
He was a hell of a frontman. RIP. https://t.co/UgyyWdbRsG

Very sad to hear about John Mann. He was a beautiful, mischievous dude with a deep gift as a performer. His eyes held a long tunnel of light, and he shared it generously with all who came in his orbit. Canada is lesser and Venice has sunk.— dave bidini (@hockeyesque) November 21, 2019
John Mann was an unbelievable performer and a great, kind man. I will miss him so deeply. My love goes to Jill and everyone in the @sotwcanada family. Playing Save This House loud in Toronto tonight. pic.twitter.com/XwS8H3u6gu— Tom Power (@tompowercbc) November 21, 2019
I'm never sure how and when to use the word "beloved". Except when describing John Mann, who couldn't be mentioned without using it. Fond memories will stay with all who knew this "beloved" member of Canada's music community and who feel his loss tonite.— Dave Hodge (@davehodge20) November 21, 2019

I cherish the memory of a Butchart Gardens concert, hearing Spirit of the West, after John Mann's diagnosis. He was so talented; so brave. #RIP— Elizabeth May (@ElizabethMay) November 21, 2019
So saddened to hear about the passing of John Mann. Such a beautiful voice, brilliant musician, powerful artist, and truly wonderful human being. Our heart goes out to Jill and the kids.— Brent Butt (@BrentButt) November 21, 2019
I was lucky enough to have seen #JohnMann perform several times over the years. The last time he used an iPad to help with the lyrics but he was as great as ever. Thanks for the music, never giving up & for sharing your story. Gone Home for a Rest too soon. RIP pic.twitter.com/rBy7u60iPN— Mark Critch (@markcritch) November 21, 2019
