In the year of 2015, the University of Toronto Students' Union filed a lawsuit against Hudson and the outgoing President, Yolen Bollo-Kamara and Vice-President Cameron Wathey. The lawsuit demanded Hudson return $277,508.62 in severance pay and overtime, paid on dismissal from her position as student union executive director and approved by Bollo-Kamara and Wathey, alleging that the dismissal prior to the end of her period of tenure was without legal basis and that she was not eligible for overtime payments.[7][8] The lawsuit had alleged that Bollo-Kamara and Wathey “breached their fiduciary duty” by signing off on 2,589.5 hours of overtime for Hudson, which was included in the severance package upon the termination of her contract. 1,974.5 hours of those 2,589.5 overtime hours were logged in a single entry on April 1, 2015.[9] The severance pay and overtime was paid in the weeks after her slate's loss in the student elections and equated 10% of the union's budget. The lawsuit sought a further $200,000 in punitive damages from the three for breach of fiduciary trust.[10][11] Hudson countersued the student union for $300,000 for breach of a confidentiality clause in her severance agreement and alleging "inappropriate conduct and unwelcome comments from UTSU directors [...] in relation to [her] perceived sexual orientation, gender and race".[8][12][13][14] The lawsuit was settled out-of-court in 2017 with Hudson agreeing to repay some of the overtime payment.[8][15]
Hudson started the Toronto chapter of Black Lives Matter after being encouraged by her brother to do something following the police killings of Mike Brown and Jermaine Carby.[16] Thousands attended a solidarity rally that she organized with Janaya Khan. After the rally, they contacted Patrisse Cullors to establish the group as the first official chapter of Black Lives Matter outside of the United States.[2] The group has challenged different forms of anti-Black racism in Canada, and has made issues like carding and defunding the police national conversations.[3][17][18][19]
