Can I come back Canada without having a job letter on my work permit?

[Sahil1999]

I got my work permit. I don't have any job right now and I won't be able to find one due to covid. However, I need to go India in emergency. Can I go and come back on my work permit without having a job offer letter. Do I need a job offer to come back to Canada?
Can anyone please let me know the solution of my problem?
I am looking for a answer.
Thanks
