Spider Jones needed time to grieve before he was ready to talk about his friend and former sparring partner Muhammad Ali.

"The world is grieving," Jones said from Toronto of Ali, whose death on Friday caused a global outpouring of grief. "He was a great man.

"I met him in 1966 when he came to fight George Chuvalo and he was the most famous person in the world, but he treated me like an equal."

Ali left his mark on Canadian sports history with his pair of victories over Chuvalo, including the memorable 1966 clash at Toronto's Maple Leaf Gardens when The Greatest was embroiled in a controversy over his resistance to the Vietnam War.

The first was a bout that turned Chuvalo into a national hero simply for staying on his feet for 15 rounds against the quickest and most gifted boxer of the era. For Ali, who died Friday at the age of 74 after a long battle with Parkinson's disease, it was a chance to show he would not be bowed by those calling for him to be banned from the sport.

The second fight came in 1972 at the Pacific Coliseum in Vancouver, where Ali vowed to be the first to knock Chuvalo down, only to see the Toronto fighter he once called the Washerwoman absorb his blows without falling for another 12 rounds. Chuvalo never went down in 93 pro bouts.

By 1981, Ali was a shadow of his former self when he lost the final bout of his career to former heavyweight champion Trevor Berbick of Halifax in Nassau, Bahamas.

Jones, of Windsor, Ont., met Ali at the gym where the champion was working out ahead of the first Chuvalo bout. Trainer Angelo Dundee asked him to join the team of sparring partners.

"I thought I'd be humiliated, but when I climbed in the ring he said 'push me around. Push me in the corner and work on me.' He was lightning fast, but he never hurt me once."

When Ali learned that Jones was sleeping at the gym, he got him a room in the same hotel as the rest of the entourage.

Jones counts himself lucky to have been up close to not only one of the greats of the sport, but an international legend.

"He was a legitimate hero, an icon," said Jones. "He was a symbol of courage."

As in the rest of the world, there was an outpouring of tributes to Ali.

Prime Minister Justin Trudeau joined the chorus of admirers.

"He thrilled. He rumbled. He fought fearlessly, and stood firm in his beliefs. He was, no doubt, the Greatest. RIP Champ," said Trudeau on Twitter.

Fate -- and a determination to stand up for his anti-war principles -- brought Ali to Canada.

Chuvalo thought he had lost his chance to face the charismatic Ali when he lost to Floyd Patterson in 1965, but then Ali's career took a turn after he was ruled eligible to be drafted by the U.S. Army. Ali refused, famously saying "I ain't got no quarrel with them Viet Cong."

He had been booked to fight Ernie Terrell in Chicago on March 29, 1966, but amid outrage from U.S. war veterans, the Illinois State Athletic Commission declared the bout "illegal" because of Ali's "unpatriotic" stance. No other state would sanction the bout, and Terrell pulled out when it looked like there would be little money to be made.

So Ali's handlers, led by Bob Arum promoting his first fight, looked north. Montreal backed out when veterans threatened to boycott Expo '67, but Harold Ballard, owner of Maple Leaf Gardens, took it on. Chuvalo accepted the fight with 17 days notice.

Chuvalo was seen as a second-tier fighter at the time, but won over both the international boxing media and the Canadian public for his courage in the ring.

Most scored the bout 13 rounds to two in Ali's favour, but Chuvalo's relentless attacks and granite chin instead made him a hero in defeat.

"He showed Canadians weren't soft," said Lennox Lewis, another former heavyweight champ who fought at the Olympics for Canada before changing his allegiance to Britain.

After news of Ali's death, Lewis tweeted: "A giant among men, Ali displayed a greatness in talent, courage & conviction, that most of us will EVER be able to truly comprehend. .RIPAli."

It took Chuvalo years to appreciate what he had done.

"When people say 'You must be proud of the fight' I say 'Proud of what? I lost the fight,"' he told journalist Stephen Brunt in his 2002 book "Facing Ali." "But in a crazy kind of way it made Canadians feel good. Kind of proud. I made my fellow Canadians proud about being Canadian and that part makes me feel good."

Times had changed by 1972. Ali was arrested for draft evasion in 1967 and didn't fight for four years until his conviction was overturned and he had become a hero to a new, mostly anti-war generation. He was battling his way back to the top when he faced Chuvalo in Vancouver.

The result was the same, a lopsided Ali victory, but he admitted afterward that Chuvalo was "the toughest guy I ever fought."

Former world middleweight champion Otis Grant of Montreal said Ali "transcended sports.

"Not even to mention his boxing, the guy was phenomenal. There's no one else in any sport that has had the impact on the world that this guy had. From being imprisoned for not going to war and later on to be given the Medal of Freedom by the U.S. president and being named peace ambassador by the United Nations. Which athlete has done anything even near what this guy has accomplished? I don't think we'll see another athlete like that in this lifetime."

Boxing promoter Yvon Michel recalled meeting Ali in the athlete's cafeteria at the 1996 Olympics In Atlanta. Michel was coach of Canada's team and Ali asked if he could sit with them because there weren't many empty seats, then spent half an hour sharing stories and jokes.

"It was a privilege," said Michel. "He's the biggest sports personality in history."
