Is Underground Fighting Legal in Canada? The Legal Verdict
No. Underground fighting is illegal in Canada, and the prohibition is unusually explicit compared with the UK gray area. Section 83 of the Criminal Code of Canada makes it a criminal offence to engage in a prizefight, to promote or organize one, or to attend one as a spectator. A "prizefight" is defined broadly as an encounter or fight with fists or hands held without lawful authority. Because the ban is written into federal criminal law rather than left to case law, there is far less ambiguity here than in many other countries. The only fights that are lawful are those that fall inside the statute's specific exceptions.
The legal verdict, in detail
Section 83 of the Criminal Code criminalizes prizefighting in three directions at once:
- Fighting in a prizefight.
- Promoting, organizing, or assisting in arranging a prizefight.
- Being present at one as an aid, second, surgeon, umpire, backer, or reporter.
That last point matters: in Canada, attending or working a prizefight is itself an offence, not only fighting in it. This is stricter than the position in many jurisdictions where spectators are at lower risk.
The statute then carves out exceptions. The amendments made in 2013 (via former Bill S-209) modernized section 83 and clarified which contests are lawful. In broad terms, the lawful categories are:
- Boxing matches with gloves, held with the permission or under the authority of the relevant provincial or territorial athletic body.
- Amateur combat sports on a program of a recognized international or multi-sport organization (for example, sports on the Olympic or Commonwealth Games program), where the province permits them.
- Other combat sports that a province or territory has specifically designated and that take place with the permission of its athletic commission.
This is the mechanism that made professional MMA lawful in Canada: provinces had to designate it and license it through their athletic commissions. Where a province has not designated a given combat sport, holding it can still be a prizefight offence.
So the verdict is layered: regulated, commission-sanctioned combat sport is legal; everything outside that, which is precisely what "underground fighting" means, is a Criminal Code offence.
Why bare-knuckle and no-rules events are illegal
Bare-knuckle boxing is not gloved boxing, so it does not fit the boxing exception, and no Canadian province has designated and licensed pro bare-knuckle the way US states have. That means a bare-knuckle prizefight in Canada is an offence regardless of medical provision or fighter consent. The same applies to no-rules warehouse fights of the kind documented elsewhere on this site: they are prizefights under section 83 and carry criminal exposure for fighters, organizers, and even attendees.
Consent does not rescue any of this. Canadian criminal law, like English law, does not allow a person to consent to fights that intentionally cause serious bodily harm outside the recognized sport exceptions. The leading authority on consent and assault, R v Jobidon (1991), confirmed that you cannot consent to a fistfight that causes serious hurt, separate from the specific prizefight statute.
What is actually legal
The lawful routes in Canada are narrow and clear:
- Sanctioned boxing, licensed by the relevant provincial or territorial commission.
- Sanctioned MMA, where the province has designated and regulates it (Ontario, Quebec, and others do).
- Amateur combat sports on a recognized multi-sport program, where provincially permitted.
For anyone drawn to combat, these are the legal options, and they come with the medical and officiating safeguards that underground fights lack entirely.
How this compares
Canada is closer to the strict end of the spectrum. Where the UK sits in a gray area with no statute and no regulator, and where more than 30 US states have affirmatively licensed bare-knuckle boxing, Canada keeps a federal criminal prohibition with defined exceptions. The result is that there is no lawful underground fight in Canada, and the law reaches organizers and spectators, not just fighters.
A note on safety
Beyond the legal exposure, underground fights in Canada carry the same physical risks documented everywhere: no pre-fight medicals, no weight matching, no ringside physician, no insurance. The Criminal Code structure exists in part to push combat into supervised, commission-regulated settings where those safeguards apply.
