The appellant, a Quebec chicken producer, grossly exceeded his allotted production quota and exported the bulk of his surplus to Ontario.
The provincial marketing board reduced his quota to zero and imposed a monetary penalty.
The appellant challenged the constitutionality of the provincial component of the federal-provincial chicken marketing scheme, arguing it could not apply to production destined exclusively for the interprovincial market.
The Supreme Court of Canada dismissed the appeal, holding that the provincial legislation is constitutional as its pith and substance relates to the local control of agricultural production, and any effect on extraprovincial trade is incidental.
The Court also upheld the federal body's delegation of regulatory powers and referential incorporation of provincial legislation.
