The joint 2002 World Cup created logistical headaches, prompting Federation Internationale de Football Association to question whether to consider multiple hosts ever again.
It will also no doubt make the case that a joint bid allows for more resources to host the expanded tournament.
The joint bid is the first to formally declare their candidacy to host the 2026 World Cup.
CONCACAF made the decision to support the bid at its congress in Aruba at the weekend with US Soccer federation president Sunil Gulati Gulati shortly to appear with his US and Mexican counterparts Victor Montagliani and Decio de Maria at a news conference in NY.
"We look forward to welcoming the world after what we hope is a successful bid".
Canadian football's head honcho Victor Montagliani is also president of Concacaf, football's governing body for North and Central America and the Caribbean.
Organizers say 10 games would be played in Canada.
And, although the U.S., Mexico and Canada each would have the infrastructure to host the tournament individually, Montagliani said a joint bid would be "a fit" for the new format.
But much work remains to be done.
What was revealed was a tentative breakdown of the amount of matches that would take place in each country.
CONCACAF has not hosted the World Cup since the tournament was played at nine USA venues in 1994.
US fans (R-L) Lindsay Beeder, 19, Shayda Ansari, 21, Lauryn De La Torre, 19, and Paige Conway, 18, react during the 2014 World Cup Group G soccer match between Germany and the U.S.at a viewing party in Hermosa Beach, California June 26, 2014. He is especially pleased that Mexico is part of this bid - and that's in the last few days we've gotten further encouragement on that. He said that President Trump has given his backing to the proposal and was particularly supportive of Mexico's involvement.
The countries that hosted the last two World Cups built massive, expensive stadiums in locations where there were no large professional teams to fill them afterwards. The final that year was played in Pasadena's Rose Bowl. Gulati said at the announcement in NY that the US would host 60 games - including every game from the quarterfinals on - while 10 each are played in Mexico and Canada.
Canada, who have only made one World Cup appearance when they were eliminated in the first round of the 1986 finals, has never hosted the tournament. That event was controversial for its use of artificial turf fields, which are banned from the men's tournament.
