A Chinese talk show host has blasted the Canadian Tourism Commission for what he said was an attempt to censor his show.

Host and musician Gao Xiaosong said on his Sina Weibo account that the release of an episode on iqiyi.com, an online video platform, had been "delayed indefinitely" because of "strong obstructions" from the commission.

The episode was supposed to be available on Friday. After a preview of the episode, which includes content about aboriginal people in Canada, the commission blocked its release, Gao said on Weibo, where he has nearly 40 million followers.
