It must be such a difficult time for your family. Your parents still need visa approval. If you are a PR or citizen, your parents don’t need authorization so not sure if going through paperwork for compassionate reasons will expedite the process.
But you may be able to both at the same time to get get authorization from the Public Health Agency of Canada (Link provided). As I said you need the doctor to fill out forms that your partner is critically ill and sign off from the hospital to be allowed to enter.
Examples of compassionate reasons can include:
- being present during the final moments of life for a loved one
- providing support to a person deemed critically ill
- providing care to a person who medically requires support
- attending a funeral or end-of-life ceremony
