I want to mail my return, but when I select that its only the federal, where do I find a pdf version of all the schedules and Ontario tax return part?

The version of the return that you mail to the CRA is condensed, so while it includes your provincial information, it doesn't include each and every form.  

To see your Ontario tax returns, you would need to look at the archive version of your return that you could download before the Mail/Netfile page.
