From Canada Post:
We continue to adjust our response to COVID-19 to protect and support our people, with employee health and safety always our highest priority. Effective immediately, we are making paid Quarantine Leave available to all employees aged 70 and older across Canada, until further notice. This same Quarantine Leave will also apply to all employees with pre-existing medical conditions or considered
high-risk (e.g. compromised immune systems, employees who are pregnant and have been instructed by a health professional to self-isolate).
