Institute for Canadian Values ad controversy

On September 24, 2011, the National Post, a major daily newspaper in Toronto, Ontario, Canada, ran an advertisement paid for by the Institute for Canadian Values (ICV). The advertisement argued against the teaching of LGBTQ-related sex education topics in the Ontario school curriculum, and was criticized for alleged discrimination against transsexual, transgender, intersex, and two-spirited people. It was supported by the Canada Christian College, which houses the ICV.

Following the controversy, the National Post apologized for the advertisement on September 30 and withdrew the ad from circulation. Two days after the National Post’s apology, on October 2, 2011, the Toronto Sun, a major Toronto conservative newspaper, ran an abridged version of the ad, derivatives of which also ran on subsidiaries of the Sun's then-owner, Sun Media. The Sun refused to apologize for running the ad, arguing it was a "principled defence of freedom of speech", though their publisher apologized and stated the Sun had agreed to never run the ad again.

The advertisement was heavily criticized by the LGBTQ community in Canada.
