I just want to say that on most farms, seasonal agricultural workers are prevented from unionizing under a Quebec regulation that says there have to be three employees working year-round before they can unionize. This year, there are three farms where Mexican workers tried to unionize, but they were prevented. At present, there is a proceeding to challenge that regulation. There may be unionized businesses, but most of the seasonal workers can't do that.
On April 10th, 2008. See this statement in context.
