Actually, if there's a `flag' regarding sponsor eligibility, it very well could impact the OWP.Aquakitty said:http://www.cic.gc.ca/english/department/atip/requests-atip.asp
It costs $5 and takes at least 30 days.
I'm thinking that CIC inquired about your sponsor which triggered the request for the $3500. At least this means they are looking at it. That would explain the sponsor delay, but not the work permit delay.
If they received your application in May, what do you mean by they only got it "4 months after (you) sent it in to them"?
Even though it's based on the submission of an Inland application, if CIC has concerns about the sponsor's eligibility, it could be an issue:

As of December 22, 2014, open work permits may be issued to eligible applicants under the SCLPC class at an earlier stage in processing. This pilot project will end on December 21, 2016.
Officers will issue open work permits to SCLPC class applicants if they meet the following requirements:
a permanent residence application has been submitted under the SCLPC class;
a Canadian citizen or permanent resident spouse has submitted a sponsorship application on their behalf;
the SCLPC class applicant resides at the same address as the sponsor; and
the SCLPC class applicant has valid temporary resident status (as a visitor, student, or worker).
Applicants whose application for permanent residence is being processed under the spousal public policy (subcategory “PP” in GCMS) on the basis that they do not have a valid temporary resident status are not eligible to be issued an open work permit under the pilot project. They must wait until they receive approval in principle to be eligible to apply for an open work permit.
Case processing centres will ensure that the requirements are met and conduct a systems check to identify any adverse information on either the sponsor or the applicant that would render the applicant ineligible to receive an open work permit. If there is information that an applicant is inadmissible, their application for an open work permit will be refused.
