North American Sheep Shearing Challenge

In 1867, the Fathers of Confederation began weaving the fabric of our nation.  In the 150 years since, one simple item has more than earned its stripes as an essential part of our heritage and as an enduring symbol of Canada:  the humble wool blanket.

Whether red with black stripes or the iconic cream with four solid bands of colour – whether made into a shepherd’s coat or an Olympian’s toque, it instantly says “We are Canadian.  We are warm.”

In 2017, we pay tribute to the pioneers who built this great land and salute the men and women who still make every wool blanket possible today: the sheep shearers.  The equipment may have changed, but the spirit remains strong! 

Join us in celebrating Canada’s 150th Birthday at the history-making Calgary Stampede North American Sheep Shearing Challenge. Champions and challengers alike – come win your share of over $11,000 in prize money and special awards. 

Experienced shearers from around the world compete in the Open Class.  Less experienced shearers are invited to enter the Intermediate Class.  Every shearer wins money in each go-round, in our unique head-to-head duel format.  


For the first time, the CS Sheep Shearing Challenge will be held the final weekend of Stampede – two full days of sharp competition, back in the iconic Victoria Pavilion, Agriculture Barn.  

The shear-off begins Saturday, July 15 with Preliminary Go-Rounds and International Team Challenge.  All shearers are invited to a special reception after the competition on Saturday evening.  The Go-Round action continues Sunday, July 16, culminating in the Finals for both divisions and the International Team Championship.

Shearers:  Please check back for shearing schedule and entry forms.  Entries open May 1, 2017. 

Get your entry and accreditation forms in EARLY, to help us determine sheep numbers and process your park entry badges. 


Shearers are responsible for their own handpieces (worm drive), combs and cutters.  The Calgary Stampede Sheep Committee provides the Lister shearing motors, and flex or jointed drops.  Please check in early on Saturday morning to help with sorting and crutching.
