Canadian Press: 'Incredibly frustrating' visa delays could thwart another Montreal conference

"It is really an embarrassment on an international scale, and we've seen this happen before," said NDP immigration critic Jenny Kwan.

She said she's had constituents complain about visa woes, and timelines posted online suggest measures such as the event codes are not improving the department's ability to process applications.

"They said that they will learn from these lessons, and prevent it from happening again. But the reality is persisting, and if anything, it's actually getting worse," Kwan said.
