Open Educational Resources (OER) and their offspring, Massive Open Online Courses (MOOCs), are becoming important factors in achieving the "Sustainable Development Goal 4: Quality Education" ("SDG4"). The OER movement is less than 15 years old and is growing rapidly as more and more nations and institutions adopt the view that publicly-funded research and educational content belongs to the people and should therefore be open and accessible to them. Canada can play an important role in supporting SDG4 by increasing its support for OER and open education in general, both in Canada and abroad. OER can be a significant aid in ensuring inclusive and equitable quality education and can promote lifelong learning opportunities for all. OER, by their very nature as freely available and usable learning resources, can be considered important, if not essential, for supporting the expressed goals in all areas of education. From pre-kindergarten to lifelong learning, including technical and vocational training, OER can have significant impact. Governments can better support free K12 education financially because the OER are available at no cost. They can be taken "as is" or modified and they can be made available to all. This includes all levels from early childhood to secondary school. One of the biggest boosts to literacy is the open availability of OER. They not only assist in promoting literacy education, they actually can serve as an incentive. Finally, OER can be used to help ensure that all learners acquire the knowledge and skills needed to promote sustainable development, including, among others, through education for sustainable development and sustainable lifestyles, human rights, gender equality, promotion of a culture of peace and non-violence, global citizenship and appreciation of cultural diversity, and of culture's contribution to sustainable development. OER can be child, disability, and gender sensitive, and provide safe, nonviolent, inclusive, and effective learning environments for all, including diverse Indigenous communities. And if not, OER can be altered and or modified to be so.
