Recently, Walmart Canada decided to order 30 more for a total 40 as a way to electrify 20% of its truck fleet by 2022.

"The move comes as Walmart Canada continues to put sustainability at the forefront of its business operations, finding new and innovative ways to reduce its carbon footprint while continuing to focus on the critical issue of driver safety."

The first 20 Tesla Semi will be used to support Walmart Canada's fleet base in Mississauga, Ontario, while the remaining 20 trucks will be allocated to the company's recently-announced Surrey, British Columbia sustainable fulfillment center, which is set to open in 2022.

By 2028, the company would like to use only alternatively powered vehicles, which means that at least some 160 more EVs (or other alt-fueled vehicles) will be ordered at some point in the future.
