A historic day that was marred by an unfortunate incident.

The Canadian Men's National Team grabbed their first-ever win at a World Cup, taking down Qatar in Vancouver by a massive 6-0 scoreline.

Jesse Marsch made two changes to the starting lineup that drew against Bosnia and Herzegovina, as goalscorer Cyle Larin and winger Ali Ahmed replaced Tani Oluwaseyi and Liam Millar, while Alfie Jones was not in the matchday squad due to injury. Alphonso Davies was named to the bench as an eligible player.

Meanwhile, Julen Lopetegui named the same Qatari eleven that grabbed a historic 1-1 draw against Switzerland.

Right from the off, Qatar got the first chance of the game after just a minute, as Edmílson Junior failed to redirect a cross from Homam Ahmed.

Jonathan David got Canada's first shot of the game, as Mahmud Abunada saved a volley from the left side of the box.

Derek Cornelius would receive the game's first card, as he was shown a yellow card for bringing Akram Afif to the ground.

After Canada got its first corner, a beautiful cross from Alistair Johnston found Jonathan David, and after Abunada spilled his volley, Cyle Larin reacted quickest to open the scoring for Les Rouges.

It would get better for the hosts just thirteen minutes later, as Tajon Buchanan's block shot perfectly set up Jonathan David, who scored a beautiful volley into Abunada's near post for a 2-0 lead.

Right after, Canada were initially awarded a penalty after Homam Ahmed brought down Tajon Buchanan. Still, a quick VAR check gave Canada a free kick and a red card, as the Qatari left-back was dismissed after 33 minutes.

Tajon Buchanan nearly scored a third, as a Jonathan David cross found him at the back post, but the Villarreal winger was losing his balance, forcing him into a weak shot that Akram Afif cleared away.

Canada would grab a third goal before the break, as another stunning cross from Alistair Johnston found Cyle Larin, and after a superb save from Mahmud Abunada was made, Jonathan David was there to tap in the rebound to make it 3-0 for the Canadians.

Cristián Garay would blow for half-time after six minutes of stoppage time, as Canada had already sealed the game after just one half.

The second half began with a substitution, as Moïse Bombito came in for the cautioned Derek Cornelius.

Six minutes after the restart, terrifying scenes happened at BC Place Stadium, as Ismaël Koné was on the wrong end of a terrible tackle from Assim Madibo, which sparked a fight between the two nations, with the benches getting involved. Madibo was rightfully sent off, and Koné was taken to a local hospital after his broken leg was stabilized.

Nathan Saliba would come in for the Sassuolo midfielder, as Koné waved at the fans while being carted off the pitch.

Later on, Ali Ahmed was wiped out by Ahmed Fathi, and the defender was shown Qatar's first yellow card of the game as Canada received a free kick in a dangerous position.

Substitute Nathan Saliba stepped up, and he buried it into Mahmud Abunada's near post to make it 4-0, as it clipped in off the post after a beautiful curling strike got past the wall.

In his celebration, Saliba dedicated the goal to Ismaël Koné in some beautiful scenes.

Seven minutes later, Jacob Shaffelburg and Tani Oluwaseyi came on for Ali Ahmed and Luc De Fougerolles, as the young centerback provided another great performance, creating a couple of chances for Les Rouges.

It would be a comical fifth for Canada, as after a Jacob Shaffelburg shot was initially going wide, Mohamed Al Mannai would try to clear the ball, but it was scuffed, and it went in for an own goal to make it 5-0 for Canada.

The final Canadian change saw local player Niko Sigur make his World Cup debut, as he replaced Tajon Buchanan, who had an electric performance despite not having a direct goal contribution.

During the nine minutes of stoppage time, Nathan Saliba's long-range shot struck Jonathan David, but he beautifully controlled the ball and put it past Mahmud Abunada to become the first Canadian to ever score a hat trick in a World Cup, making it 6-0 in the process and also becoming the first player from a host nation to score a hat trick since Geoff Hurst did so in 1966 for England.

That was it, as over 50,000 fans in Vancouver witnessed Canada grab its first-ever win in a Men's World Cup in fine style, even despite the injury to Koné.

With this result, Canada find themselves at the top of Group B, as they are tied with Switzerland on points, but edge them in the goal difference category thanks to the big win in Vancouver.

Now, Canada controls its own destiny heading into the final group stage match against Switzerland, as a win or draw will see Canada top the group, with a loss dropping them into second place or potentially third place if Bosnia and Herzegovina heavily defeats Qatar plus Canada loses heavily.

The two sides will meet in Vancouver next week on Wednesday at BC Place Stadium, with kickoff set for 12:00 pm PT / 3:00 pm ET.
