Gold Star father Khizr Khan, whose speech last year at the Democratic National Convention (DNC) made waves, is unable to attend a speaking event in Toronto because his "travel privileges" are reportedly "being reviewed," CTV News first reported.

The luncheon organized by RamsayTalks was to have featured Khan, who is Muslim and a U.S. citizen, talking about "what we can do about the appalling turn of events in Washington—so that we don't all end up sacrificing everything," an advertisement for the midday event states.

But a Facebook post Monday afternoon from RamsayTalks says the event is now canceled, and it includes a statment from Khan who says he has "not been given any reason as to why" his travel privileges are being reviewed. It states:

CBC political reporter John Paul Tasker also tweeted Monday afternoon that Khan was scheduled to appear Tuesday on CBC radio show "The Current" during his time in Toronto.

"This turn of events is not just of deep concern to me but to all my fellow Americans who cherish our freedom to travel abroad," Khan says SCROLL TO CONTINUE WITH CONTENT Never Miss a Beat. Get our best delivered to your inbox.

During his speech alongside his wife, Ghazala, at the DNC convention, Mr. Khan, whose son U.S. Army Captain Humayun Khan was killed in action in Iraq, directed a critique at then-candidate Donald Trump saying, "You have sacrificed nothing and no one."

"Let me ask you, have you even read the United States Constitution?" Khan asked Trump. "I will gladly lend you my copy. In this document, look for the words, look for the words, liberty and equal protection (under) law."

Days after the convention, the Khans gave an interview with MSNBC in which Mr. Khan criticized U.S. wars in Muslim nations as leaving us in a "quagmire," "more vulnerable," and creating "chaos for ourselves."
