Alert: Loblaws is selling GM tomatoes

June 2026: The GM tomatoes were also spotted in a few Giant Tiger stores in New Brunswick, and could have been sold in other Giant Tiger locations.

The GM tomatoes are sold in clear plastic boxes branded as the “Empress” tomato. They are not clearly labelled as genetically engineered but carry the US “bioengineered” symbol with a note that the tomatoes are “Patented Technology”. The tomatoes are produced and distributed by the large greenhouse producer Red Sun Farms, headquartered in Kingsville, Ontario.

Read and share our new Consumer Alert (April 24, 2026).

Take Action

1) Tell Loblaws and Giant Tiger to remove genetically engineered “Empress” purple tomatoes from their shelves and commit to a 100% non-GMO produce section so that you know what you are buying.

In Ontario and the rest of Canada – Click here to call or email Loblaws.
In Nova Scotia – Click here to call or email Loblaws.

Let CBAN know. Please tell us about your action and send us any response from your grocery store. Contact Fionna at outreach@cban.ca or 249-532-0340 
You can refer store managers and produce managers at all stores to our newly updated Guide to Securing a Non-GMO Produce Section.

2) Write to Red Sun Farms: Red Sun Farms is the big greenhouse company that is growing and marketing the GM purple tomatoes in Canada. They are grown at Red Sun Farms’ greenhouse in Kingsville, Ontario. Ask Red Sun Farms to stop growing GM tomatoes. Tell them you will not buy any of their other tomatoes until they stop producing GM tomatoes. Send your message here. You can also call them at 1- 800-286-0691.

Protect Our Produce

Companies are testing consumer and farmer acceptance to launch new genetically engineered (genetically modified or GM) fruits and vegetables, some developed with the new genetic engineering techniques of gene editing.

A genetically modified purple tomato is now being sold in Canada. There are three other genetically modified fruits and vegetables on the market in Canada, with a very marginal presence in grocery stores: GM sweet corn, GM papaya, and GM pink pineapple. Until now, genetic engineering in our diets has been dominated by processed food ingredients from GM corn, GM canola, GM soy and GM sugar beet. If customers and farmers do not take action now, there are a number of genetically modified fruits and vegetables that could soon be released into our food system and seed supply.

You can help Protect Our Produce and take action to advocate for a Non-GMO Produce Section in your grocery store.

More Information

April 21, 2026: Loblaw Companies Limited is the first company in Canada to sell genetically modified tomatoes. The GM purple tomatoes have been sighted in stores in Nova Scotia (Superstore) and Ontario (Loblaws). In June 2026, the GM tomatoes were also sold at reduced prices at Giant Tiger locations in New Brunswick, and could have been sold at Giant Tigers in other provinces.

These are transgenic tomatoes that were genetically engineered with two genes from snapdragon flowers, to increase the plant’s anthocyanin production which also makes the tomato purple. Anthocyanins are a type of flavonoid that has antioxidant properties. There are already non-GM tomatoes on the market that have these same properi

Biotechnology companies want to release a new flood of genetically engineered (genetically modified or GM) fruits and vegetables made with the new genetic engineering techniques of genome editing, also called gene editing. These techniques are new ways to genetically engineer plants and animals to express new traits. Tools such as CRISPR aim to delete DNA segments or otherwise change a DNA sequence. Unlike traditional plant and animal breeding, genetic engineering makes changes directly to the genetic make-up of organisms in the laboratory. Gene editing can also speed up the development of new genetically modified organisms (GMOs).In Canada, these new GMOs can be released without government safety assessments or labelling for consumers. In 2022 and 2023, the federal government removed pre-market regulation for most gene-edited seeds and the foods from those plants, such that these new GMOs can enter the market without a government approval process and without any mandatory notification to the government or public.

If customers and farmers do not take action now, there are a number of genetically modified fruits and vegetables that could soon be released into our food system and seed supply. See cban.ca/GMFoods for more information.

Updates

December 2025: Health Canada and the Canadian Food Inspection Agency have approved a genetically modified (GM or genetically engineered) Purple Tomato™ for increased anthocyanins in the fruit. Unlike many future gene-edited GMOs that are exempt from pre-market regulation, this GM tomato was assessed for food safety by Health Canada.
