On The Mark Publishing started as S & S publishing by a Canadian primary school teacher named Ruth. She created lots of educational workbooks and materials specifically geared to Canadians. In 2005, the company merged with On The Mark, and today, their website has a HUGE list of Canadian subjects:
- Famous Canadians
- Story starters
- First Nations
- Discovering different communities
They have many reasonably priced resources – both for Canada and the US.
