Rules & Guidelines

The Junior Slam Series takes the health and safety of the participants in our events as our number one priority. As part of this policy, all Junior Slam Series events follow the world standard concussion protocol and return to play policy. In addition, Ontario legislation, entitled “Rowan’s Law” requires that all athletes, guardians and coaches review the concussion awareness training at least once per year. Links to the training materials can be found in the Rowan’s Law section on this page. As part of complying with Rowan’s Law a second page has been added to our season waiver that must be signed by ALL guardians, athletes and coaches prior to participating in any of our events.

Any athlete who, at any of our events, is involved in or is a witness to an incident as described in this protocol is required to immediately report the incident to the event convenor. That convenor will assess the risk of concussion, and, if necessary recommend additional assessment. They will also file an incident report.

Any athlete who is involved in an incident, prior to a Junior Slam series event, where a concussion is diagnosed, will be required to provide a doctors note that certifies that they have followed the 5-step process outlined in the protocol and have proof that they have received medical clearance to return to play.

The Junior Slam Series convenor has the ability to file an incident report at any of our events.

The Junior Slam Series has a zero tolerance policy for bullying. This applies to athletes, coaches, parents and spectators attending and participating in a Slam event. Every team is responsible for the behaviour of the individuals in its group. For example, if a parent contravenes this policy, it applies to the entire team. This policy applies to behaviour at a Slam as well as to cyber/online references to Junior Slam Series competitions and participants.

Failure to comply with this policy may result in removal from the Slam competition and/or from all future Slams in the curling season and competition fees will not be refunded. Interpretation of this policy is at the discretion of Junior Slam Series. Zero tolerance means one infraction may result in disciplinary action.

Bullying and Unwanted Behaviour Policy

At the Junior Slam Series, we are committed to creating a competitive environment that is safe, respectful, and developmentally appropriate for all participants — including athletes, coaches, officials, volunteers, and spectators. Our goal is to foster high-performance growth rooted in sportsmanship, integrity, and mutual respect.

Bullying is defined as any intentional or repeated behaviour — physical, verbal, psychological, social, or digital — that causes harm, distress, intimidation, or exclusion to another individual or group. Bullying may occur in-person or online, and can involve one or multiple individuals, whether acting directly or passively. It is also important to note that any unwanted behaviour that causes someone to feel targeted, unsafe, or humiliated may be considered bullying, regardless of whether it was intended as “just a joke” or competitive intensity.

In a curling context, bullying and other inappropriate conduct may include (but is not limited to):

• Using one’s body or brush to deliberately obstruct an opponent’s view or path of delivery;

• Taunting, name-calling, or mocking athletes in locker rooms or off-ice spaces;

• Spectators or coaches verbally confronting or intimidating other attendees;

• Athletes or coaches threatening, insulting, or dismissing convenors or volunteers;

• Sending disrespectful, intimidating, or harassing messages through social media or text;

• Coaches belittling athletes in a way that causes emotional distress;

• Spectators harassing club staff such as kitchen teams or ice makers.

On-Ice Conduct and Celebratory Behaviour

We also ask all participants to be mindful of excessive celebrations, theatrical reactions, or “grandstanding” behaviours that may be common in other sports but are not aligned with the values of curling. While we celebrate passion and joy, gestures that are intended to draw attention, embarrass opponents, or shift focus away from team performance to individual display are discouraged.

Examples of unacceptable celebratory conduct include:

• Yelling, fist-pumping toward opponents after a missed shot;

• Prolonged shouting, dancing, or over-the-top celebrations that disrupt the flow of play;

• Overly dramatic gestures that appear meant to taunt or show up other teams.

At the Junior Slam Series, we believe there is a difference between expressing joy and undermining respect. Our standard is not to suppress enthusiasm, but to channel it in ways that uplift your team and honour your opponents. Respectful celebrations are part of the game. But curling remains a sport grounded in humility, honour, and grace — especially in moments of victory.

Reporting and Accountability

All participants — athletes, coaches, parents, volunteers, and spectators — have a duty to report incidents of bullying, harassment, or inappropriate conduct to Junior Slam Series staff. Reports will be handled with confidentiality, care, and urgency.

We acknowledge that bullying is more likely to occur in high-pressure and emotionally charged environments. While the drive to win is an important part of athlete growth, we remain committed to creating competitions that are first and foremost safe, developmental, and inclusive. These values define who we are and what kind of champions we aim to build — on and off the ice.

Except where noted below, Junior Slam Series events follow Curling Canada’s Rules of Curling for General Play.

Team Makeup

For U18 & U20  events, all teams are single gender. U15 teams are open and may be any combination of players. Mixed Doubles teams require one player of each gender.

No spares/alternates are allowed in Mixed Doubles. Mixed Doubles teams are earning points in a qualification process. Any change in lineup before the event begins constitutes a new team. Changes in lineup during an event are not allowed in Mixed Doubles events.

On September 16, 2016, The World Curling Federation issued a statement on rules, specifications and policies for sweeping techniques and brush technology for elite curling.  Herewith, all teams participating in the Junior Slam Series must abide by the World Curling Federation (WCF) standard for brushes and sweeping.  This applies to all Slams in our series with NO exceptions.

Most equipment manufacturers have a full supply of approved brush heads in stock. 

The Junior Slam Series introduced the Junior Team Ranking System (JTRS) for U15, U18, and U20. All teams that compete in a Junior Slam Series event automatically earn JTRS points in the age category of that event.  The JTRS points are used to invite teams to “Invitational Events” offered by the JSS.  Provincial points systems are available for qualification to the various Provincial Association events. i.e Ontario’s TTRS system.

For our Mixed Doubles events we have created the MDTRS system which is based on field size.

Junior Slam Series events adhere to the Spirit of Curling. The Spirit of Curling is a commonly used term that refers to the respect curlers show, not only to one another, but also to the sport itself. It is encapsulated by the principle that a curler would rather lose than win unfairly. Respect is one of the fundamental principles which underpin the Spirit of Curling. Slam competitors are expected to uphold the spirit of curling on, and off the ice. The Spirit of Curling generally sees no player attempt to gain an advantage in the game through any malice, whether by breaking the rules, distracting opponents or acting in an unsporting manner, which would effectively disadvantage their opponents. It is expected that if a player should do so then they admit to their fault. Broom slamming, profanity and unsportsmanlike behaviour are not acceptable.

The Spirit of Curling demands good sportsmanship, kindly feeling and honourable conduct among coaches and spectators too. This spirit should influence both the interpretation and application of the rules of the game and also the conduct of all participants on and off the ice.

The Spirit of Curling plays a crucial role in Slams, where there are no referees or officials, however Slam conveners will keep events running smoothly and help to iron out any concerns. Rules are based on the Spirit of Curling and every curler should adhere to this etiquette when playing.

Every member of the team must review the full competition guidelines & sign a waiver (athletes, or athlete’s parent/guardians and the coach). Once every team member has signed, waivers can be scanned and emailed to waivers@juniorslamseries.com. Please email us ALL the signed waivers for every member of your team together under one email. Alternatively, you may sign the waivers and bring them to your first Slam. Teams will not be permitted to play without ALL the athletes and coach signing and submitting this waiver.

Important: The Concussion Code of Conduct is different for Coach and Athletes. Make sure you download the correct version, sign and date BOTH the waiver and Concussion Code of Conduct.
