I didn’t apply on spousal sponsorship I applied for a BOWP and it is listed as an extension when I called before and they said it is listed as an extension and the processing time appliesUnfortunately that processing time doesn't apply to OWPs submitted with inland spousal sponsorship applications. That processing time is for other classes of work permits applied for from within Canada. We used to see people get their work permits within the 3-4 month range. However since this new year, this has increased to 4-5 months typically. See IRCC info here:
