More than a one-day event, We Day is the movement of our time-a movement of young people leading local and global change. We Day is tied to the year-long We Act program, which offers educational resources, campaigns and support materials to help turn the event's inspiration into sustained activation. Through We Act, students commit to taking one local and one global action to better the world, earning their way to We Day. At We Day Toronto, 20,000 youth, educators and friends will be inspired to make a difference, both in their own community and overseas.
