It doesn't matter where you go to get your fingerprints done. As long as RCMP does recognise them. I was just using your statement about Hamilton to judge that you were in the province of Ontario.
You can and should absolutely apply for OHIP. There is a 90-day wait before it becomes active. So, applying now would be to your benefit. The AIP letter does permit you to apply. You do need to make sure you have the required documents, as stated in the links I pasted previously.
When you land, you just go to Service Ontario, and update them (show them your COPR, which will be handed to you, when you land) and they will have you fill out an update form (you just check the PR box) to make your OHIP permanent.

You must be able to answer "yes" to at least 1 of these statements:
Canadian Citizens and Permanent Residents
- You are a Canadian citizen or permanent resident.
- You are a "protected person," also called a convention refugee.
- You are registered as an Indian under the Indian Act. (This is for aboriginal people of Canada.)
- You applied for permanent residence and Immigration, Refugees and Citizenship Canada (IRCC) confirmed that you meet the eligibility requirements to apply for permanent residence in Canada. This means that you have "approval-in-principle."
- You have applied for a grant of citizenship under section 5.1 of the Citizenship Act (Canada). IRCC confirmed that you meet the eligibility requirements to apply for citizenship. (This is for children adopted internationally by Canadian citizens.)

I took the liberty of highlighting the important part...
When you land, the officer will send an application in for you, for your first PR card. That will take ~61 days to arrive. This is reasonably consistent, and you can see that metric here:
http://www.cic.gc.ca/english/information/times/ (select 'Permanent Resident Cards + No I am waiting for my first card). That's the safest and easiest bet. HOWEVER, you can leave before that time, if need be. You will need to apply outside Canada, at an embassy or visa office for a Permanent Resident Travel Document (PRTD), UNLESS you are from a country where there is no visa / eTA required.
When you land, you are in this grey area, where all the visas you may have had, immediately become invalid (it's not legal for a PR to have Canadian visas -- they are not required for PR's). So, I would suggest waiting for the card. But if you cannot, there is a means to be able to return to Canada, as I said above.
So, with what I said above: if you landed in February, you could potentially return in February. This would require an additional fee for a PRTD, an additional application, and several weeks of processing time. OR, you could wait ~61 days (assuming you land February 28th; you should have your card by ~April 30th -- and don't tell
@sylvain1 that I was date-mathing after 11am!).
