Canada must continue pursuing its sustainable development agenda and address pressing challenges, including weak productivity growth, persistent socio-economic inequalities, and the need to reduce net greenhouse gas emissions to zero by 2050, as set out in its ambitious environmental plan. Canada has historically been open to investment and trade. The stock of foreign direct investment (FDI) as a percentage of gross domestic product (GDP), highlighting the economic importance of foreign investment, has increased over time and is higher than that of most other OECD countries. The largest share of FDI is found in services, particularly in the management of companies and enterprises, finance and insurance and trade. Some manufacturing sectors, particularly chemicals, food and beverages, petroleum and coal products), and gas and oil extraction have also received significant foreign investment, particularly in the form of expansions and new establishments of foreign companies (i.e. greenfield FDI). Other sectors such as manufacturing, agriculture, utilities, and construction attract relatively lower levels of FDI in Canada. The majority of greenfield FDI projects are situated in Ontario, Alberta, British Columbia, and Quebec, which are the most densely populated provinces and centres of economic activity.
