Our Mission

The Ontario Alliance of Climbers is an independent provincial, volunteer non-profit organization that works diligently to keep climbing and bouldering areas open.

The Bolt Fund is Live!

The OAC Bolt Replacement Fund assists route developers with the costs associated with replacing aged or worn out fixed hardware. Bolts and anchors may show wear, rust or damage after prolonged use and exposure. Replacing this gear is vital to improve climber safety and accessibility.

On May 3rd, climbers came together at Rattlesnake Point and Mount Nemo to participate in our annual Spring Fling crag clean up day! 

The past few years we were happy to see limited amounts of trash at these crags, but this year the hauls were quite large!  Garbage found included broken chairs, random bricks, and steel bars in addition to the usual broken bottles and discarded wrappers. We had about 45 volunteers who diligently spent the morning picking up litter, celebrated with a pizza lunch provided by @conservationhalton , and then got some climbing in on a very sunny day ๐Ÿ˜Ž

We'd like to extend a big thank you to everyone who came out and gave back to the community, and to Conservation Halton for helping us host the event!  We'd also like to extend a big thank you to @ontarioresoles who donated a half resole and rand repair to the volunteer who picked up the most trash, as well as two @orgearco gift certificates we raffled off ๐Ÿ† 

We can't think of a better way to kick start the climbing season, than with a great day of crag care ๐Ÿฅฐ  See you out there on the walls!

The amendment to the Devilโ€™s Glen Provincial Park Management Plan has officially been approved! ๐ŸŽ‰

This is a major milestone -- not just for climbing access, but for how outdoor recreation and conservation can work together. The updated plan includes policies to formally authorize and manage rock climbing in the park, creating a path forward for safe, sustainable access. This is a big step forward, and it sets an important precedent for climbing in provincial parks across Ontario.

This outcome reflects years of work and being a good partner with Ontario Parks, the Ministry of the Environment, Conservation and Parks, and the Ontario Alliance of Climbers (OAC). Itโ€™s also a testament to the climbing communityโ€™s commitment to stewardship, safety, and respect for the environment.

Weโ€™re excited for what comes next! The OAC looks forward to continuing to work alongside Ontario Parks to support implementation โ€” through education, stewardship, and responsible use.

Thank you to everyone who contributed, supported, and stayed engaged throughout this process. Your actions have had a direct effect on climbing access in Ontario!

More details to come soon. You can read up on the decision details at the link in our bio ๐Ÿ”—

And just like that, the outdoor season is upon us! 

As you head back out to enjoy Ontario climbing, keep an eye out for aging or questionable hardware.  Especially when heading out early in the year, you are more likely to be the first one to go up a route in months!

Weโ€™ve made it easy to report bad hardware through our website - helping local developers see what needs attention and keep our routes safe.

Spot something that doesnโ€™t look right? Let us know (๐Ÿ”— link in bio).

Letโ€™s work together to keep our crags -- and each other -- safe ๐Ÿง—โ€โ™‚๏ธ
