Covid 19- 62 y/o T1 healthcare worker- refusal of work? or stress leave? ontario, canada

I am here on behalf of my mother, 62 y/o breast cancer survivor with T1 diabetes she is working on the front lines as a phlebotomist at a lab. (Taking blood samples, contact with patients).

I am deeply concerned for her with the covid 19 risk. Over 5000 healthcare workers just in Italy and China have been infected due to the unavailability of full hazmat suits. Her work place has regular masks (they don't have enough of the n95 masks to use them all the time) they are wearing gowns, gloves and faceshields. But these measures proved insufficient in other countries.

She has told her boss that she doesnt feel comfortable with the high risk of her health, since she is more vulnerable than others. They refuse to put her on modified duties. And told her, the PPE they provide is sufficient. Our family and others in the healthcare really feel that she should be sent home because of her age and vulnerabilities.

I am searching for thoughts and advice. I've asked her to see if she can take a leave of stress. But her doctor recently retired...

so I'm interested On steps I can recommend she can take.
