Early goals saw Canada and Honduras win their opening matches of the Confederation of North, Central America and Caribbean Association Football (CONCACAF) men's Olympic qualification tournament, where COVID-19 complications left Haiti shorthanded.
Honduras won the first of two matches at Guadalajara's Estadio Jalisco, dispatching Haiti 3-0.
Haiti had to start the game with just 10 players and an outfield player in goal while they waited for coronavirus test results, however, because many of the squad arrived in Mexico late.
The Haitians could only bring on a full-time goalkeeper mid-game, once his coronavirus test came back negative.
Darixon Vuelto opened the scoring from the penalty spot with 14 minutes gone and Edwin Rodríguez doubled the advantage four minutes later, finishing calmly after beating the offside trap.
Vuelto added a third goal before the interval, reacting sharply to the makeshift Haiti's goalkeeper's deflection on a cross to guide the ball home, and that was how it finished.
Canada followed that with a 2-0 win over El Salvador and Tajon Buchanan was the star man.
The New England Revolution player opened the scoring after 17 minutes, shimmying past his marker before scoring from a tight angle with a low, left-footed drive.
And four minutes later he doubled the Canadian advantage in style, with shades of a famous Wayne Rooney goal.
Buchanan fell to the floor after colliding with an El Salvador player off the ball and was complaining to the referee as play continued - only to pick himself up as the ball headed his way and unleash a vicious strike - this time with his right foot - from outside the box which sailed into the top corner.
Canada held on to win 2-0.
Honduras and Canada each have three points from one game and are in command of Group B.
The group's top two sides will advance to the semi-finals, and the winners of those matches will advance to Tokyo 2020.
The CONCACAF berths are the last two places at the men's Olympic football tournament to be decided.
