About Us

Flexahopper Plastics is a 100% Canadian owned and operated rotational molding plastics company founded in 1967 and headquartered in Lethbridge, AB.

Our History

In 1967 Flexahopper Plastics Ltd. was established in a small hanger at the Lethbridge airport.



In 1973, Jim Spenceley packed up his family and moved across Canada, from Ontario to Alberta, to take the reigns of Flexahopper Plastics Ltd.

At the start of 1982, Jim’s son Bill Spenceley joined Flexahopper Plastics in an executive roll.



In the late 1980’s Flexahopper Plastics was able to secure a new, larger facility located in the Industrial Park of Lethbridge, AB.

The acquisition of the new plant came with many benefits and upgrades. One of the biggest advantages was the opportunity to have material delivered directly to the facility by rail car and stored right into our silos.



Flexahopper had penetrated several markets such as agricultural, oil and gas, water storage and fishing.

The early 2000’s saw an expansion of the current facility to include a much larger secondary warehouse that included indoor tooling storage.



Flexahopper Plastics committed to sourcing only renewable energy for their operations resulting in a partnership with Bullfrog Power (https://bullfrogpower.com/)

 Through the next decade, Flexahopper grew exponentially, reaching new countries and succeeding in different markets.



2017 was an exciting year for Flexahopper! Not only was it the 50-year anniversary of the company but it was also the year that the largest solar array in the industry was installed at the plant.

Bill Spenceley becomes a Hall of Fame recipient for Association of Rotomolders.



Flexahopper’s in-house laboratory was renovated and expanded, first- class technology and world-wide research takes place at this facility.

We are committed to leading the industry with innovation while caring for and supporting our environment.  



We are proud to work with great companies and we invite you to explore their products and services.
