I was able to apply outland with proof (only by receipt of payment) of a medical done - twice, actually - within Canada without any problem. The important thing is that the overseas embassy knows where the medical was done, and that the DMP sends the results to the proper Regional Medical Centre so that the embassy can request them. As long as your DMP was aware that you were processing outland, s/he should have been aware of the fact that they needed to be sent along to the RMC that serves your embassy. All inland applicants have their results sent to the RMC in Ottawa, and the majority of Canadian DMPs see inland applicants - so it might be worth a call to the DMP just to find out which RMC they sent your results to. Some of the overseas embassies are also served by the Ottawa RMC (like the USA), but not all. Since you don't say which embassy would process your outland ap, I can't say which RMC should have received your results.
I submitted a rather long response to you question about inland v outland
in that thread, but an outland applicant
can get "implied status".
"Implied status" is not about having applied for permanent residence. I think you're misunderstanding what the term means and thinking, mistakenly, that an inland ap automatically gives the applicant "implied status" to remain in Canada . . . it doesn't. I've explained it better in the other thread, but in order to benefit from "implied status" you have to first
have valid temporary status, and then you have to submit an application to extend that status so that CIC receives the application before the status expires. If someone applies for PR inland, they
include the extension application
with the inland PR ap, and it gives them "implied status" to continue under the terms of their original status - as long as the package is received before the expiration of the temporary status. If someone applies outland, they simply send the extension application to CIC separately, with proof of the sponsorship PR application and the qualifying relationship. The important thing is that either extension is received by CIC before the temporary status expires - that's what gives the "implied status" to remain in Canada until they make a decision on the status extension. The status you can extend into (ie visitor, work permit, study permit) is what's different when you extend by virtue of an inland sponsorship, or an outland one. For example, if a visitor applies for PR inland, they can ask to change their conditions to an Open Work Permit and, after the first stage of assessment is successfully completed, they will be issued an OWP. But they have to remain a visitor until first stage is done - nearly a year now. If they already have a work permit, applying inland allows them to extend that permit and continue working for the year it takes to get first stage and an OWP. However, if someone with a work permit applies for PR outland, they are not eligible to extend their existing work permit and continue working under "implied status" - they have to change their conditions to visitor, and remain in Canada only as a visitor under "implied status", either until PR is granted, or until their status expires (extend again) if they're still waiting. There's more detail in the other thread that's specific to your working holiday visa as well, but I don't believe a WHV is extendable.
