Mining Taxation Regimes

The Canadian tax rules applicable to the mining industry are unique (click here for a general description of federal income tax rules that are specific to mining). Their uniqueness stems from the presence of three significant levels of taxation (see taxes and levies by level of taxation) and from a long-standing recognition of the specific characteristics of mining.

Mining is a highly cyclical and capital-intensive industry, with a long lead time between initial investment and commercial production. Accordingly, the federal and provincial income tax systems, as well as provincial mining taxes, provide a generous treatment of exploration and other intangible expenses, and allow mining companies to recover most of their initial capital investment before paying a significant amount of taxes (see our section on tax incentives for mineral production ). The income tax regime also provides for generous loss carry-over rules to help mitigate the negative financial effects of fluctuating prices. Finally, a unique characteristic of provincial mining tax and royalty regimes is that they are principally based on net production profits rather than on the net smelter return royalties commonly found in other countries.

While Canada's mineral taxation regime has been stable for many years, it is not static. It keeps up with important trends in the industry, such as globalization, more holistic environmental and social responses, increased Aboriginal participation in mining, and optimization of recycling (see our section on mining taxation issues for a discussion of these topics). However, significant changes are always implemented through a transparent consultative process to ensure that tax rules affecting the economics of new projects are known before massive amounts of capital are committed.
