Resource Tax:  

Canada is known for its abundant natural resources: vast oil and gas reserves, rich mineral deposits and expansive forests. The taxation of these important resources is an area of unique complexity. Corporations engaged in resource extraction are subject to special rules and statutes that impose additional taxes and complexity (over and above the usual tax rules that apply to all businesses). Canada is also well known for its capital markets that finance resource acquisitions and exploration around the world. In addition, many Canadian-based (and foreign-based) companies expand to conduct foreign mining operations from (and through) Canada. In this respect, Canada’s comprehensive 'foreign affiliate' tax system adds even further layers of tax complexity for companies engaged in these industries.
