In 1996, Del Grande was charged under Ontario labour law by the Ontario English Catholic Teachers' Association for "bargaining in bad faith" when it was alleged that he used the local media to manipulate public opinion at a time when the school board was in contract negotiations with its teachers.

On November 7, 2019, during discussions to update the TCDSB Code of Conduct to match the Ontario Human Rights Code and be more inclusive and protective of LGBTQ2S+ students by adding specific terms gender identity, gender expression, family status and marital status, Del Grande stood up to move an amendment asking for several other terms to added including bestiality, pedophilia and terms related to rape, cannibalism and vampirism to be added to the list.

Facing severe backlash, including a public petition made with over 2,100 signatures as of December 2019, his proposed amendment was eventually ruled out of order and was withdrawn.
