Answer:
Thanks for the question. This is very similar to another ASKMAC question from 2012. The process for a paramedic to withhold initiating resuscitation is clearly outlined in the Do Not Resuscitate (DNR) Standard training bulletin.
This document can be found here:

This exact situation is reviewed in the Training Bulletin produced by MOHLTC in Appendix 2 named ironically Frequently Asked Questions.
Question 17 on page 26 states: “For the paramedic or firefighter to not perform CPR on a patient who is in respiratory or cardiorespiratory arrest, he/she MUST receive a fully completed DNR Confirmation Form. This Form is the only directive that gives permission to paramedics and firefighters to not perform CPR on patients who have a DNR order and have experienced respiratory or cardiorespiratory arrest”.
