But bygones could not be bygones for these two aging warriors.
When the pair are called to the stage, Mr Kapp offers Mr Mosca a flower as an olive branch. Mr Mosca rejects the offer and tells his opponent: 'Stick it up your a**!'
Mr Kapp, instead, decides to shove the flower up Mr Mosca's nose. The defensive lineman bats Mr Kapp's hand away.
The former quarterback lurches toward Mr Mosca. Mr Mosca swings with his microphone, then his cane. The cane connects with Mr Kapp's head.
At this point, the audience, which had been laughing hysterically, falls silent as it realizes the two elderly men on stage are not playing around.
Mr Kapp moves in and punches Mr Mosca in the jaw, knocking him to the floor. As he's down Mr Kapp seems to land one good kick.
About 30 seconds in, younger, more responsible men rush the stage and tear the two elderly football players apart.
Both men had careers long after the infamous 1963 game. Mr Angelo went into professional wrestling after developing a reputation as the meanest player in Canadian professional sports. Mr Kapp became the only quarterback to play in the Rose Bowl, the Superbowl and the Grey Cup.
"I don't want to pass judgement on Angelo Mosca or Joe Kapp but I think there is a lesson to be learned here. The trick to life is to lighten the road, not pile it on," comedian Ron James, who was the host of the luncheon, told CBC Sports.
"But these guys, despite their age, what is bred in their bones is a warrior's streak."
