Not sure if you're tapping maple trees in Canada, but this is about Quebec, specifically the "Strategic Reserve" of the Quebec Maple Syrup Producers [1].
In general, Canada allows for controls on the supply-side in agriculture, including limiting imports. The alternative is to take the approach used in the U.S. of allowing prices to fall to unsustainable levels but then providing cash subsidies to producers. There has been a decades-long conversation about this between the two countries, of course.
