The best sap year at Coaticook was 2020 with 57 freeze-thaw days; the leanest was 2015 with 21. Seasons that start early tend to end early too: the trees run on the swing between freezing nights and mild days, and heat ends it.

Maple production

Coaticook in the Census of Agriculture

Statistics Canada counts the farms that report maple taps in its Census of Agriculture every five years. In 2021 it counted 157 in Coaticook, with 891,643 taps; in 2016, 138 farms and 676,700 taps. Among Quebec's 61 census divisions with a published tap count, Coaticook ranks 16th, and 17th of the 94 in this atlas.

Over the five years the farm count changed +14% and taps +32%. Statistics Canada cautions that 2021 and 2016 are not strictly comparable: the census-farm definition changed in 2021, and farms were assigned to their main location more strictly.

Statistics Canada doesn't publish syrup volume by census division, so the Canadian pages show farms and taps, not gallons or litres.

PPAQ regional fact sheet, 2026

The Producteurs et productrices acéricoles du Québec (PPAQ) publish a fact sheet for each sugaring region, with figures for every MRC. These are from the 2026 Estrie sheet. They count enterprises registered under the joint marketing plan, by where the sugarbush is; the census above counts 2021 farms by their main location. The two sit side by side here and are never added together.

About these numbers

The season dates are estimated from 35 seasons of daily high and low temperatures for the Daymet 1-km grid cell at Coaticook, the division's most populous municipality in the 2021 Census; the cell sits at 293 m (961 ft). Each day is scored with the same freeze-thaw rule as our live forecast: a sap day is an overnight low under −1 °C (30.2 °F) followed by an afternoon high over +3 °C (37.4 °F). A season's closing signal is the last sap day before accumulated warmth reaches a threshold, and the opening signal sits 35 days before that, never earlier than the first real freeze-thaw week. The rule was calibrated on 117 state-seasons of USDA-reported dates in the US and is applied here unchanged. In Quebec it reproduces the pattern between regions in producers' reported seasons (Houle et al. 2015), and the typical dates are anchored to that record. Production figures are copied from Statistics Canada as published; the PPAQ figures, from its 2026 regional fact sheet, are shown separately.

Coaticook sugaring questions

When should I tap maple trees in Coaticook, Quebec?

How much maple syrup does Coaticook produce?
Statistics Canada doesn't publish syrup volume by census division.
