The Lazy S Ranch is a 1000 head cow-calf operation that’s been in the beef business for 50 years.
Located West of Edmonton, Alberta in the Mayerthorpe area, it is owned and operated by Stewart and Doreen
Ainsworth and their family’s, consisting of sons Grant and his sons Carson and Jace, Greg and his
wife Tracey & son Jade, and daughter Donna and her husband Larry and their daughters Shaylyn &
Lindsay. Daughter in law Claire runs the local Vet Clinic in Mayerthorpe and Whitecourt.
Our cowherd has been a work in progress for the past 48 years…retaining the top end replacement heifers
and putting them back into our cowherd for four and half decades, has allowed us to cull harder on the cowherd
and rewarded us with a phenomenal set of productive cows that we are so proud to own today.
We are a seed-stock operation that annually markets 200 plus breeding bulls in our annual Bull Power Sale the
last Saturday of January.
Lazy S Ranch raises three breed lines of cattle - Red and Black Simmental, Angus and SimAngus
Beefmakers. They are red and black in color and packaged in polled look-a-like groups with a large
selection of bulls to choose from at an affordable price.

Lazy S fed steers.
We add value to our own calves by finishing out the bottom end home raised steers and heifers, this
provides us with valuable information how our cattle perform on feed and on the rail.
Lazy S Ranch is a self-sufficient ranch, growing its own feed, annually consisting of 5000 acres of grain and
legume silage, along with dry hay.
Over the past four and half decades, we have marketed over 4500 bulls to customers based from British
Columbia to Prince Edward Island and ranches in the United States.

July 13, 1943 – October 2, 2021 It is with great sadness that the family share the passing of Stewart
Jackson Ainsworth. Stewart was a devoted husband to Doreen and father to Greg (Tracey), Donna (Larry
Arthur), and Grant (Claire). He will be profoundly missed by his grandchildren Jade, Shaylyn, Lindsay,
Carson and Jace. Stewart is also survived by his brothers Marvin and Max Ainsworth. Stewart was born in
Rimbey to Kelsa and Ruby Ainsworth. His love for farming and cattle began at a young age and grew from
there. He was a lifelong rancher who took great pride in his family and farm. He worked hard for many
years to create a ranch name and quality cattle that fit his very strict specifications! He instilled that
same work ethic and pride in his children and grandchildren, which will live on for generations. Stewart
grew up in Byemoor, Alberta and married Doreen in 1967. At that time he worked for the Lacombe AI unit,
AI'd cattle at the Bull Pound Community pasture and surrounding area, as well as starting their own cattle
herd at the same time. In 1977, Stewart and Doreen moved the family North to Mayerthorpe and established
Lazy S Ranch. Over the years, Stewart, Doreen and the family developed a quality purebred Simmental herd
and had their first Lazy S Bull Sale in 1969. Stewart was extremely proud of the bull sales that have
continued on now for over 50 years. He really enjoyed the friendships he made through the cattle
industry.... delivering bulls and getting to know other ranchers across Canada. Family was always very
important to Stewart. There was always time for family fun in things like 4H and team penning, but there
was also still work to do! Even if the kids came home late, Stewart always made sure they were up and put
to work right away... the cattle came before sleep! In the later years, he still impressed that work ethic
on his grandchildren, who he was so proud of and loved deeply. An online memorial will be announced at a
later date. If you so wish, memorial donations in Stewart's name can be made to the Young Canadian
Simmental Association. #13, 4101-19 St NE Calgary, AB, T2E 7C4. 403-250-7979. Care entrusted to Bear Creek
Funeral Home 780-830-7742 bearcreekfuneral.com
