This is simply not true.

If someone refused to use a preferred pronoun — and it was determined to constitute discrimination or harassment — could that potentially result in jail time?

It is possible, Brown says, through a process that would start with a complaint and progress to a proceeding before a human rights tribunal. If the tribunal rules that harassment or discrimination took place, there would typically be an order for monetary and non-monetary remedies. A non-monetary remedy may include sensitivity training, issuing an apology, or even a publication ban, he says.

If the person refused to comply with the tribunal's order, this would result in a contempt proceeding being sent to the Divisional or Federal Court, Brown says. The court could then potentially send a person to jail “until they purge the contempt,” he says.
