Maple production

Les Jardins-de-Napierville 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 41 in Les Jardins-de-Napierville, with 78,672 taps; in 2016, 22 farms and 25,412 taps. Among Quebec's 61 census divisions with a published tap count, Les Jardins-de-Napierville ranks 53rd, and 62nd of the 94 in this atlas.

Over the five years the farm count changed +86% and taps +210%. 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.

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 Saint-Rémi, the division's most populous municipality in the 2021 Census; the cell sits at 56 m (184 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. Full method, the Daymet checks and the Quebec validation → Run a sugarhouse here? Put this sap forecast on your own website →
