The full method for checking a fish consumption advisory in Quebec: use the MELCCFP official guide, find your water body, read the recommendations by species, size and group, and what to do if the lake isn't listed.
The question comes up every time you bring a nice catch home: is this fish safe to eat? In Quebec, you don't guess the answer — you look it up. The government publishes an official tool that tells you, water body by water body and species by species, how many fish meals you can safely eat. This guide walks you through how to check a consumption advisory for a specific lake. To understand why these advisories exist, start with our mercury and consumption guide.
Key takeaway — Consumption recommendations come from the MELCCFP's Sport Fish Consumption Guide. You look up your water body, read the recommended number of meals by species and by size, and apply the column that matches your group (general population, or women of childbearing age and children). When in doubt, always choose the more cautious option.
Why check a consumption advisory?
Some contaminants — especially mercury — build up in fish flesh over the years. You can't see it, taste it, or cook it away. A fish can look perfectly healthy and still carry levels that warrant limiting how many meals you eat. That is exactly what a consumption advisory does: it turns lab analyses into a simple instruction — how many meals per month, and for whom.
Where to find the official information
The single reference in Quebec is the Sport Fish Consumption Guide, produced by the Ministry of the Environment (MELCCFP). It compiles analysis results for hundreds of water bodies across the province. You can reach it from our official consumption guide page, which gathers the useful links and explanations. Skip Facebook groups and hearsay: only the government source is reliable and kept up to date.
Checking a lake, step by step
- Open the MELCCFP consumption guide.
- Search for your water body by name. Large lakes and rivers are often listed individually; watch for duplicate names (many Quebec lakes share the same name) — check the administrative region.
- Find your species. Recommendations vary enormously between species. Walleye, northern pike and muskellunge — all predators — generally accumulate more contaminants than small prey species.
- Look at the size. This is a key factor (see below). The guide gives recommendations by length class.
- Pick the right column for your group. One column targets the general population; the other, more cautious, targets pregnant women, those of childbearing age, and children.
- Read the recommended number of meals and adjust your catch accordingly.

Why fish size matters
Within the same species, a big fish is almost always more contaminated than a small one. The reason is simple: a larger individual is older, it has spent more years feeding and accumulating mercury, and if it is a predator, it has eaten many other fish that already carried contaminants. That is why the guide breaks its recommendations down by length range: a small walleye may be allowed more often than the trophy of the season. Keeping medium-sized fish for the table and releasing the very large ones is both a cautious strategy and one that benefits the resource.
If the water body is not listed
Many small lakes have never been sampled and therefore do not appear in the guide. A lack of data is not a guarantee that there is no contaminant. In that case, apply the general cautious recommendations the guide provides precisely for unlisted water bodies: they act as a safety net. It also helps to know which species carry the most risk — our article which fish accumulate the most mercury helps you decide which ones to limit first.
In short
Checking a consumption advisory takes two minutes and always follows the same logic: the right source (the MELCCFP guide), the right water body, the right species, the right size, and the right column for your profile. When uncertain, caution wins. These notes do not replace the official guidance, which always takes precedence. To go further on fishing in Quebec as a whole, see our complete guide.
