Hi, I am in a similar situation. Were you able to work it out then ?
Yes, I used my 'implied status letter' for job change.
I found this in IRCC website.
(i) If you apply for renewal of your work or study permit and your permit expires before a
decision is made, paragraph 186(u) and section 189 of the Immigration and Refugee Protection
Regulations provides you the right to continue working or studying under the same
conditions, pending a determination of your application for renewal, as long as you remain in
Canada. This is referred to as “implied status”. You will have implied status until a decision is
rendered by the IRCC, which means you are allowed to work even though your SIN has
expired.

If you have an employer-specific work permit and you want to change jobs or employers, you
must apply for a new work permit from inside Canada. International Experience Canada (IEC)
participants must first check that they can change employers with an IEC work permit.
Due to COVID-19, you don’t need to wait until your work permit application is approved to start
your new job or work for a new employer. You just need an email from IRCC that says you have
permission to change jobs.
As always, open work permit holders can change employers at any time.
