These production numbers are always skewed to grossly incorrect for many reasons on both sides of the border. I fill out the census report each year but many don't because they feel the "government has no business knowing production". They fail to see benefits to the industry what counts are accurate. Many feel that the tax man will knock on their door if a count is submitted. There are others that just fall thru the cracks, usually smaller producers, but lots of small producers added together with lots of others would likely generate some staggering numbers on both sides of the border. This is not to dispute that Quebec is the largest maple producer by a huge margin, it just tries to point out the errors in any count.
In regards to a Federation type set up on this side of the border, I really enjoy things as they are. I want a free market system.
