About the OTCC

OTCC 2022

As of 22 March 22, the OTCC 2022 will be moving forward at Springbank Park, City of London on  Friday, September 23, 2022 @ 4:00 pm until the completion of the Masters on September 24, 2022.

ISAO is still watching COVID numbers, and while we plan for the event, we will be in contact with the Public Health Officials, the City of London, and the OTCC Committee.

Climber registration opens 7am – Monday, July 11th. Registration will close at midnight Monday, July 25th. In due course, all registrants will be notified of their place in the queue. If 10 women are not registered, extra spots will be filled by men on the waiting list to reach the 35 participant maximum and vice versa.

  • Climbers must be members of ISA Ontario, in good standing, at the time of registration.  Membership application will NOT be accepted at the time of OTCC registration;
  • Climbers must be present for mandatory role call, gear check and climber orientation on the afternoon of Friday, 23rd September.

OTCC 2021

The situation for the OTCC 2021 is, at the moment, undetermined.   We have booked Springbank Park in London, Ontario for September 10th & 11th.

Any decisions made on whether the OTCC will move forward in 2021, will be taken under consideration from Public Health Officials, the City of London, and the OTCC Committee.

We hope to make the decision by early June.

Thank you for your patience.


OTCC 2020

The ISA Ontario Board of Directors has, on the advice of the OTCC Committee, made the difficult decision to cancel the 2020 OTCC, due to COVID-19. After long and thoughtful discussion, balancing the importance of this annual event as both a gathering of the industry and a venue to showcase the best of our industry, versus our social responsibility to act in a way that casts the best light on our industry, the OTCC Committee feels this is the best course of action.With TCI Expo and ITCC setting the examples of cancelling their events, and the unpredictable nature of the COVID-19 landscape coupled with the vast amount of protective policies, procedures and equipment needed to satisfy health and safety concerns, the Committee was left with no alternative.Please know, this was an incredibly tough decision for the OTCC Committee to make. We understand that many people in our community look forward to this event, as athletes, volunteers and spectators. This is why we had to make this decision; to keep everyone safe and healthy. While saddened about this decision, we hope that you all understand the reasons why. We are appreciative of your support.

As we begin taking steps to prepare for the 2021 event we will continue to provide updates to keep everyone informed.

About OTCC

The Ontario Tree Climbing Championship provides a regional platform to showcase arborists’ proficiencies in tree climbing while simulating working conditions of arborists in the field, based on judging criteria established from industry best practices and safety standards.  The competition is also an opportunity to introduce the latest climbing techniques and innovations in equipment, in a controlled, safe environment where it can be judged by a panel of experts.   At the same time, the OTCC facilitates an environment of interaction between ISAO members and other supporters of the community, such as equipment manufacturers, suppliers, trainers, researchers, and business owners in order to promote worker safety and training.  Lastly, competitive tree climbing introduces the public to the skills professional climbing arborists must use for safe, professional tree work.

The OTCC is held in different parks throughout Ontario; Arborists who compete come from all over the province, to demonstrate their skills in 5 preliminary events: Work ClimbBelayed Speed Climb, Simulated Aerial Rescue, Throwline and as of 2019, ISA Ontario will introduce the Ascent Event.  Secured Footlock is still being offered by some Chapters.

The top 4 men, and top 2 women competitors from the preliminaries advance to the Masters’ Challenge, a final event where the male and female Champions are crowned.  The Champions go on to represent ISA Ontario at the annual International Tree Climbing Championship.

The OTCC is a fantastic spectator event and is free to the public! A tradeshow of arborist equipment is featured and spectators can try climbing like an arborist in the “Climb For All Ages” under the guidance of a professional arborist.  For further information please call 1-888-463-2316 or email [email protected].
