Before I address the thrust of the OP, post modernism, I'll add something to the current discussion on whether Canada's C-16 will include pronouns and misgendering as discrimination.
The Canadian Department of Justice website says that they will look to the various human rights commissions for help, and that the Canadian Human Rights Commission will ultimately decide the boundaries of the law:
From the Ontario Human Rights Commission website:
If the Canadian Human Rights Commissions follows in the footsteps of Ontario, which the fact that they directly referenced it seems to suggest, then C-16 will make "misgendering" and the refusal to use chosen pronouns proscribed discrimination.
As for prison, the law, as noted, allows the HRC's demands to be orders of the federal court. According to rule 466 of the Canadian Federal Court disobeying an order of the court is contempt which may result in imprisonment for a period of less than five years or until compliance.
Federal Courts Rules
Will it ever get to that point? I certainly hope not. But, the law allows for it; until rulings come down deciding how this will be handled the concern is valid.

Questions and AnswersDefinitions of the terms “gender identity” and “gender expression” have already been given by the Ontario Human Rights Commission, for example. The Commission has provided helpful discussion and examples that can offer good practical guidance.
From the Ontario Human Rights Commission website:
“misgendering” is a form of discrimination
The Tribunal found misgendering to be discriminatory in a case involving police, in part because the police used male pronouns despite the complainant’s self-identification as a trans woman.
Questions and answers about gender identity and pronounsRefusing to refer to a trans person by their chosen name and a personal pronoun that matches their gender identity, or purposely misgendering, will likely be discrimination
