Thank you very much for your question.
When the government commits to something, it must be able to meet that commitment. The bill states that the Government of Canada commits to providing an estimate periodically, but it will need whatever tools are necessary to do that.
You asked if the school boards could be required to provide that data. The answer is no, because the school boards are under provincial and territorial jurisdiction. Therefore, the federal government cannot encroach on that jurisdiction and require provincially regulated school boards to provide any records.
