Front-of-package labels are already shaping shopper behaviour
Canada’s new front-of-package (FOP) nutrition warning labels are often discussed as a regulatory deadline. That framing misses the real story. The impact of FOP labels, mandated by Health Canada, will not be felt all at once; rather, their impact is emerging—measurably and unevenly—and is likely to compound as consumer familiarity grows.
Early shopper data shows FOP labels are operating as a behavioural accelerant layered onto existing decision dynamics rather than a replacement for them. Price and promotions continue to dominate choice in a value-constrained environment, with 61% of Canadian shoppers selecting price-related factors as one of their top three drivers when choosing packaged food or beverages, according to Caddle research. Nutrition, however, remains firmly embedded in the decision set, cited by 32% of shoppers as one of the most important on-pack considerations. This distinction matters. FOP labels do not need to displace price as the primary decision driver. By attaching a highly visible nutrition signal to products that are otherwise price-competitive, FOP labels act as a cognitive filter, increasing scrutiny at the moment of comparison.

Awareness of FOP warning labels is still developing. Fifty-six per cent of Canadian shoppers say they are aware of the FOP labels, while 44% are unaware. Actual exposure is lower still: fewer shoppers report noticing a FOP label during their most recent grocery trip. This gap between awareness and recall is often misread as lack of relevance. In reality, most consumers are still forming mental models of what these symbols mean and how much weight to give them. That makes context (shelf placement, adjacent claims, pricing and digital presentation) especially influential at this stage.
Despite this partial awareness, FOP labels are already influencing stated behaviour. When shoppers are asked how a FOP nutrition warning would affect their purchasing, 57% say it would influence their decision, including buying the product less often, switching to a different option or avoiding it altogether. Importantly, this level of stated impact appears before FOP labels have reached full saturation and while price sensitivity remains elevated. The implication is clear: FOP labels do not require universal understanding to alter behaviour. Even early exposure is sufficient to drive change for most shoppers.
Broader shopping behaviour data reinforces this point. In the past three months, nearly three out of four Canadian shoppers report changing how they shop for groceries, signalling a consumer environment already open to reassessment rather than locked into habit. FOP warnings are entering a market where shoppers are actively recalibrating value, health and trade-offs, not passively repeating prior choices.
The influence of FOP labels is expected to intensify as familiarity grows. When asked to look ahead, shoppers indicate that FOP warnings will play a larger role in how they compare products and make final purchase decisions once the labels become more common. This effect is particularly pronounced among millennial shoppers, who are more likely than older cohorts to say FOP warnings would change their purchasing behaviour. While millennials do not represent the entirety of grocery spend, their responses provide a clear signal of where expectations and norms are heading.
One of the most consequential implications of FOP labelling is its uneven impact within categories. Products that once competed primarily on flavour, familiarity or promotion will now be separated by a binary nutritional signal. As a result, some SKUs will remain relatively insulated, while others (often high-velocity, high-margin items) may face disproportionate pressure as shoppers substitute alternatives with fewer or no warnings.

Retailers are likely to see these shifts first through substitution behaviour: changes between branded and private-label products, changing responses to promotions and evolving basket composition. In digital grocery, the effect may be amplified further. Online shelves compress choice and place products side by side, making FOP warnings more salient and harder to overlook when compared directly against price, ratings and claims.
FOP warning labels are not a one-time disruption. They represent a change in how shoppers process information at the shelf. The evidence already shows influence before full awareness. As familiarity turns into habit, that influence is set to reshape category performance across Canadian grocery.
