To order your B.Ed./Dip.Ed. transcript for the OCT, the simplest way to do so is via the OUAC at: https://webapp.ouac.on.ca/webapp/oct_macros/oct_trf.d2w/report?merchant_rn=182971. This method gives you the option of having it sent after degree conferral, which is what the OCT requires. It is also sent electronically which is faster than sending a paper copy.
You can also get to this link via the OCT’s How to Apply at https://apps.oct.ca/OLR/Template.aspx?action=rege.
