Mark Carney, the Canadian prime minister, said IRGC members are “prohibited from coming” when asked about the issue earlier on Thursday.
Speaking to reporters he said he was unable to comment on the specifics of individual cases under the country’s privacy laws, but noted the IRGC has been listed as a terrorist organisation in Canada for several years.
“There are multiple hurdles in order to get into the country and I think the important thing is that those hurdles are effective,” added Carney.
The Iranian football federation has not yet commented on its absence.
Foreign affairs minister Anand added: “My understanding is that there is a revocation of the permission. It was unintentional, but I’ll leave it to the minister to indicate.
“I’ll say that on our position on Iran, it is clear from a diplomatic standpoint, we have no diplomatic relationships with Iran. We have not had diplomatic relationships with Iran for over 10 years.”
The World Cup begins on 11 June with Iran due to face New Zealand and Belgium in Los Angeles on 15 and 21 June respectively, and then Egypt in Seattle on 26 June.
US President Donald Trump has previously said Iran would be welcome at the World Cup, but added they should not be involved “for their own life and safety”.
He was asked about Iran’s participation again following Infantino’s comments on Thursday and said: “Well, if Gianni said it, I’m OK. I think let ’em play.”
Iran had petitioned for their games to be played in Mexico, but Infantino has always maintained the country would take part in the tournament as scheduled.
