The leadership of DuBreton company blames a combination of the provincial hog marketing board and government income insurance for the situation.
It also repeated complaints that the marketing board makes it difficult for specialty and niche-market producers and processors such as DuBreton to compete.
The industry is dominated by a farm co-operative that owns Olymel hog-production and hog-processing company.
Within the last year, the marketing board and Olymel have both drastically down-sized the Quebec hog industry.
In the past Ontario has complained about unfair competition from Quebec, pointing to generous income supports funded by the province.
