A greenhouse in southern Alberta will be the main supplier of lettuce for Wendy's Restaurant chain in Canada. 

Whole Leaf, located in Coaldale, will be supplying zero pesticide lettuce to all 384 locations.

The year-round greenhouse operation promotes "Clean Canadian Greens" growing over 20 million heads of lettuce a year.

Lisa Deletroz, Senior Director of Marketing for Wendy's Canada says they know that greenhouse farms grow produce that hits the mark for freshness and flavour. 

"What's more, this transition will enable Wendy's to further support Canadian producers and the Canadian economy, while offering supply predictability and consistency."

Rindi Bristol, Senior Director of Sales for Whole Leaf says this strategic partnership allows us to reach Wendy's customers all-year-round with high-quality fresh produce alongside a brand that - like Inspired Leaves - is committed to quality and sustainability.

Whole Leaf's greenhouse operation includes technology that allows them to capture and reduce water consumption by over 90 per cent compared to field-grown lettuce.  

It also features an onsite process that captures waste heat and CO2 at the same time, reducing greenhouse gas emissions and allowing it to be completely self-sufficient for electricity and heating.
