Durham area dairy farmer Michael Schmidt has been found guilty of obstruction, and will be sentenced November 8th.
Schmidt was in a Walkerton court October 19th where the verdict was given by the judge.
It relates to a standoff in October 2015 at Schmidt's farm.
Farm members who were owners of the cows on-site, blocked the police and the Ministry of Agriculture and Food and Rural Affairs as well as the Ministry of Natural Resources to from taking things off the farm.
Schmidt was charged with obstruction of justice along with a few others but charges were eventually dropped against his supporters.
The criminal code calls for a maximum sentence of 2 years for a conviction on obstruction, but Schmidt says the Crown has been talking about 30 days.
Micheal Schmidt has been fighting for 22 years to get the rules changed concerning raw milk.
He says the first raid on his farm was in 1994.
A hearing in a Newmarket court involving the distribution of raw milk ended in June with the judge reserving his decision.
It has not yet been handed down.
