Many argue that the practice of fully funding separate schools exclusively for the Catholic faith is discriminatory to other religions (the United Nations has twice chastised the province for this policy).

The opposition, however, argues that this is an appeal to tradition, and point to other provinces in Canada which amended the constitution to abolish Catholic school funding.

With stalled negotiations, the TCDSB officially locked out the teachers on May 16, 2003, and the strike lasted 12 days which left 69,000 students affected.

[35] In August 2018, Gerry McGilly, 47-year-old former English teacher at Bishop Allen Academy was sentenced to 2–3 years in prison after he pleaded guilty to luring, making child pornography and sexual exploitation of his students, including three 17-year-old victims, dated between 2014 and 2017.

Iozzo had been employed by the Board since 2012 and started his teaching career at Stella Maris and St. John the Evangelist Catholic Schools.

This report offered guidelines for Catholic schools that included calling groups like GSAs "Respecting Differences" clubs and avoiding discussions of sexual attraction, political activism and gender identity.
