The Canucks will bring their maiden campaign to a close when they face Uruguay in the third-place play-off on Sunday (AEST).

Their opponent's players were involved in a post-match brawl with Colombia supporters after a semi-final defeat after violence erupted near to where family members were located.

After the CONMEBOL announced it had opened an investigation into the incident, Uruguay head coach Marcelo Bielsa insisted his players should receive an apology rather than be sanctioned.

Marsch believes the incident highlighted severe problems within the tournament, after a Canada player was subjected to racial abuse online after a Group A defeat to Argentina.

While the Canada head coach empathised with his Uruguay counterpart, he feels there would have been a stronger punishment incurred had it involved his side.

"For me, this tournament has not been professional," Marsch said. "There are too many gaps in the way.

"I watched what happened after the match, and certainly I don't know all the details, but certainly we wouldn't want anyone's families or any player's families to be put in harm's way.

"But I know if our team responded like this, that there would be heavy sanctions because of the treatment that we received in this tournament. We've been treated like second-class citizens."

Marsch also criticised the officiating after Alphonso Davies was forced off injured in Canada's semi-final defeat after a heavy challenge by Gonzalo Montiel, with the referee not even awarding a foul.

"You give me another opportunity to talk about how poor the refereeing was for the tackle on Alphonso," he added.

"If you were to turn it over and put that against the biggest player from the other team, specifically from South America in this tournament, the behaviour and the treatment for such a tackle in such a situation would be very different.

"So, we were lucky that we avoided any big injury with Alphonso, but we're not totally certain if he'll be available tomorrow. And one of the main jobs of a referee in any match is to protect the safety of players, and that was not doing his job."

Marsch has also rubbished links to the United States men's national team, insisting his commitment remains with Canada.

"I'm not leaving this job," the former Leeds United coach said. "I have no interest in the U.S. job and to be fair, unless there's a big shift in the organisation, I don't think that I'll ever have an interest in that job in the future.

"I'm really happy here. I couldn't be happier, actually, in terms of what it's like to work with the leaders in this organisation and what it's like to work with this team."

Marsch has previously hit out at United States for its treatment of him when the national side was looking for a new manager in 2022.

The Canada head coach was thought to be the leading contender after the 2022 FIFA World Cup when Gregg Berhalter's contract expired.

Berhalter was unexpectedly rehired shortly after, however, and Marsch said he "wasn't treated very well in the process" in discussions over the managerial vacancy.

Marsch has somewhat had the last laugh, with Canada reaching the semi-finals at the Copa America for the first time while United States was dumped out in the group stages.
