The document discusses financing development to achieve the UN Sustainable Development Goals (SDGs). It notes that the SDGs require development finance to "go big" by scaling up from billions to trillions. It distinguishes between "scale investors" like pension funds that need market structures to invest large amounts, and "catalytic investors" like governments and philanthropists that can take more risks. Canada can help by building on existing blended finance initiatives and reforming its development finance institution to take more risks and offer a broader range of instruments as a catalyst.
