A wave of optimism has swept the African continent in the past decade. The pace and extent of social change in recent years, when measured in life expectancy, child and infant mortality rates, literacy, numeracy and the completion of higher education, is quite remarkable. The urban middle class is emerging and expanding in many African countries, while political democracy is developing and strengthening. These positive changes are generating economic growth and attracting foreign investment across the continent, especially in the resource sector. But Africa is still viewed by many as the "dark continent" dealing with serious problems — civil wars, ethnic division, corruption, HIV/AIDS, poverty, food security and the disastrous effects of climate change — and these issues may well impede the upward trajectory of Africa. Canada-Africa Relations: Looking Back, Looking Ahead — the 27th volume of the influential Canada Among Nations series — analyzes the ebb and flow of Canada's engagement with Sub-Saharan Africa through different lenses over the past few decades and also looks to the future, highlighting the opportunities and the difficulties that exist for Canada and Sub-Saharan Africa. It is clear that a new Africa is emerging, and Canada must be prepared to change the nature of its relationship with the continent.
