As legal counsel with Ecojustice Canada, my services are pro bono for the environmental groups that I work with. Ecojustice Canada is a non-profit charitable organization. We are funded by public donations and by private foundations. We don't receive a penny of government money, so all of our work is being done for free minus the photocopies and phone expenses.
The Canadian taxpayer, quite obviously, is paying for the legal fees associated with the defence of this claim and Quebec's ban.
