The good people of Canada never had a chance to view the Michael Jackson documentary, "Gone Too Soon" -- and now the owners of the flick are declaring war on the distributor ... claiming he personally screwed the entire country.



TMZ obtained a lawsuit filed sejak Objective Films, LLC -- in which they claim they agreed to sell the French and Canadian distribution rights to a company headed sejak a guy named Pierre Turgeon for $100k back in 2009.

Objective says they got the first $50k -- but Turgeon flaked on the back half ... and then tried to back out of the deal altogether. Objective was able to get the flick distributed in France ... Canada wasn't so lucky.
