Joanna was awarded the Canadian Bar Association Sexual Orientation and Gender Identity Conference Hero Award in 2008 for her contributions to LGBTTQ communities. In 2017, she received the Law Society Medal for exceptional career achievements and contributions to her community in the areas of LGBTQ rights, family law, constitutional and human rights, and was the winner of a Lexpert Zenith Award: Celebrating Women in Law.

Joanna practices in all areas of family law, for diverse families.

Joanna was counsel to the LGBTQ families in Grand v. Ontario. She negotiated an interim order in which the Attorney General conceded the unconstitutionality of the Children’s Law Reform Act. Joanna then worked extensively with government and stakeholders on Bill 28, the All Families are Equal Act, which reconceptualised parentage in Ontario.
