Cosplay Props Policy

The Northern National Collectors’ Convention is dedicated to providing a safe and welcoming environment for everyone.

Cosplay Prop Check (Weapons Check)

Cosplayers must go to the Cosplay Prop Check at the main entrance to have props and weapons examined by crew members.

Any weapon not allowed by the Northern National considers inadmissible must be immediately removed from the convention. The decision of Cosplay Prop Check crew members is final and will be strictly enforced to ensure a safe environment for all attendees.

Failure to respect any of the weapon rules may cause any or all of the following:

  • Confiscation of weapon or item, without return.
  • Loss of admission to the show without refund.
  • Involvement of law enforcement agencies, and/or other actions deemed appropriate by the Northern National.


Weapon is defined as any item or object that the Criminal Code, crew members, or Caesars Windsor staff (if and where applicable) considers to be a weapon. 

Prohibited and/or Illegal Weapon is illegal to be possessed, displayed, or sold in Canada. Illegal weapons must be immediately removed from the convention centre. The Northern National reserves the right to notify law enforcement agencies if an illegal weapon is brought into the convention. 

Inadmissible Weapon is a non-prohibited legal weapon that has been examined by crew members and may not be brought into the convention. A legal weapon may still be considered inadmissible at the Northern National (e.g., a metal sword) and must be immediately removed from the convention. Some weapons sold by exhibitors are prohibited and are subject to the procedures in the Special Circumstances section below. 

Admissible Weapon is a weapon that has been examined by crew members and may be brought into the convention. 

Cosplay Prop Check (Weapons Check) is the area at the Northern National where all items that may be considered weapons are inspected by crew members and determined to be prohibited, inadmissible, or admissible.

Examples of Prohibited and/or illegal Weapons 

If it is illegal outside the convention, it is illegal inside the convention and therefore banned from the Northern National. Examples include but are not limited to:

  • Firearms of any kind.
  • Bali-song (“butterfly knife”) or switchblade/drop blade style knives.
  • Brass knuckles or knives/blades attached to brass knuckles.
  • Spiked wristbands.
  • Morning Stars or Flails.
  • Concealed knives or blades in normally innocuous items that are less than 30 cm in length.
  • Hand crossbows.
  • Pyrotechnical items, metal objects, or projectiles.
  • Nunchucks, tonfas, shurikens, or similarly prohibited martial arts weapons (foam replicas of these items are admissible).
  • Law enforcement items such as batons, tasers, or mace.
  • Arrows, bolts, and other projectiles used in bows, crossbows, or slingshots.

Special Note: Although some types of cane swords, umbrella swords, and similar items may not be prohibited in Canada, ALL such items are banned from display, sale, or possession at the Northern National.

Please review the Canada Border Services Agency’s and Justice Canada’s information regarding prohibited weapons.

Special Circumstances

Inadmissible Weapons Purchased from Exhibitors

Inadmissible weapons on display and/or being sold by exhibitors must be safely secured to the display surface if they are within reach of attendees (i.e., attendees must not be able to pick up the weapons). As part of normal shopping behavior, attendees are permitted to handle inadmissible weapons under the direct supervision of the exhibitor.

Exhibitors may only display (including under-the-counter displays and items stored out of sight) or sell weapons or any other items that are permitted to be sold by all applicable provincial and federal laws and regulations.

The sale of an Inadmissible Weapon to anyone under 18 years of age is strictly prohibited.

Exhibitors may only sell items to persons who are legally entitled to purchase and/or possess the weapon or item.

The display or sale of prohibited (illegal) weapons or items may result in an exhibitor being removed from the convention and/or other actions deemed appropriate by the Northern National. 


For safety reasons, exhibitors must conduct demonstrations of inadmissible weapons or other items behind the counter, table, or within the allotted booth space. 

After the Sale

Once a weapon has been sold, it must be securely wrapped in thick paper or cardboard and cannot be taken out of its packaging at the convention. It is the exhibitor’s responsibility to inform attendees of the requirement to keep their purchased weapons securely wrapped while at the convention or they will be confiscated. 

Admissible Weapons Purchased from Exhibitors

Exhibitors must inform attendees purchasing the weapon to bring it to the Weapons Check at the entrance and have it tagged as an admissible weapon. Exhibitors are required to explain to attendees that if the weapon is not tagged it may be confiscated.

Exhibitors must have prior approval from the Northern National to arrange for mock battles to show off their LARP weapons during convention hours anywhere on the convention site. Requests should be directed to

Exhibitors are reminded that all participants in mock battles must not damage the convention centre, the Northern National, or other exhibitor property and must be extremely careful not to endanger or injure bystanders.
