So are you saying that Mr. Khan is a liar - that he would cancel an important engagement in Toronto - to the inconvenience of many, pursuant to some kind of publicity stunt? The âsourceâ of this news is from Mr. Khan and the organizers of the event themselves.
And he would not be denied re-entry, he would be denied entry into Canada - becasue, presumably his passport may be cancelled - and while you can also get in Canada on a driverâs license and US birth certificate, Mr. Kahn was born in Pakistan. He probably does not want to waste the airfare.
The re-entry, of course, would probably entail some hassles too, but as a US citizen he must be let in.
