There are lots of enterprises, groups, organizations provide free resources to students in North America, also most of those resources are free to students.
Here I collect several online resources info which from school board office websites.
1: York region district students online resources:
On this webpage we can see multiple online tools and resources. For example, Microsoft and Google provide free stuff such as Microsoft Office, Google Apps for free as long as student use their own school email.
2: Toronto district school:
Here the page. but seems fewer than York region schools, I guess official site does not provide full list.
Will keep looking for more info.
