Amy Schumer expressed remorse to her Canadian fans on Tuesday after illness forced her to cancel three upcoming shows.

"I'm so sorry Canadians, sweet people," the 35-year-old comedian said in an Instagram video.

"Every night when I go onstage I promise it's going to be the best show I've ever done, and I can't make that promise because I feel awful and my voice is gone."

The impacted dates are:

Toronto - Wednesday, Nov. 9.

Ottawa - Thursday, Nov. 10.

Montreal - Friday, Nov. 11.

As of Tuesday afternoon, Ticketmaster hadn't yet confirmed the cancellations, but the Toronto venue — the Air Canada Centre — issued a statement saying that Schumer's Wednesday show has been postponed, with tickets being honoured at a later date.

Schumer's website now shows three new Canadian dates in February.

Toronto - Thursday, Feb. 16.

Montreal - Friday, Feb. 17.

Ottawa - Saturday, Feb. 18.

Refunds are also available, but fans expressed their disappointment.

'I shed a few tears'

"I was devastated to hear the news," said Kelsey Duffy, a 21-year-old student who had planned to drive from Charlottetown to Montreal with friends just for Friday's show. "I will admit that I shed a few tears," she told CBC News.

On top of the $100 she spent on her ticket, Duffy said she and her friends shelled out $450 on non-refundable accommodations. But more than the money, she's annoyed how the cancellation was handled.

"I did not receive any emails from Ticketmaster that the show had been cancelled," she said, explaining that she got the news from her cousin.

"I am extremely disappointed with how this situation was handled especially considering what a big fan I am."

Duffy was not alone. Many ticket holders were left looking for answers online.
