An investigation by Radio-Canada has uncovered evidence that a major Quebec maple syrup producer has been adulterating its products with cane sugar before selling them to grocery store chains across Canada.

The investigation began when a Radio-Canada reporter noticed an unusual taste in maple syrup he had purchased. Subsequent laboratory testing confirmed the product had been diluted with cane sugar, prompting a broader investigation by the broadcaster's Enquête investigative program.

Journalists conducted an undercover operation involving false identities and covert recordings to document the alleged fraud. The investigation focused on low-cost maple syrup products sold in major grocery store chains throughout the country.

The findings suggest consumers may have unknowingly purchased adulterated maple syrup products marketed as pure maple syrup. Quebec is Canada's largest maple syrup producer, accounting for the vast majority of the country's annual production.

The investigation highlights potential gaps in food quality oversight for one of Canada's signature agricultural products. Maple syrup production is heavily regulated in Quebec, with strict standards governing purity and labeling requirements.
