Got it

Then, unless you made a mistake in questionary, you will have to provide meds.
Assuming that you apply at the end of January, your old med will only be valid for few more weeks, which most likely will not be enough considering 8-10 weeks of "typical" IRCC processing time.
Possible options
1. Send old meds and hope some magic will happen.
Potentially, you might save some money, 200-300$,
but there is a high chance that IRCC will send a request letter for fresh meds.
Then it is a hassle - making a appointment, waiting, passing meds,
perhaps sending explanation letter to IRCC with your upcoming med check dates.
In worst case scenario, you application can be refused if it gets to a brutal officer.
2. Do your new meds to make sure your application is solid before submitting it.
I would personally go with this option. Better safe than sorry.
3. Talk to immigration lawyer. Maybe you can visit a lawyer from your school to save $$$
In this case, you can go over the "week" spots in questionary to see if there is a chance
to avoid raising med field.
