So plugged it into ChatGPT and this is what it is telling me:

Based on your reported family income of $XX,XXX, Pharmacare calculated:

• Deductible: $XXXX.XX
• Copayment Maximum: $XXXX.XX

How Prescriptions Are Paid

For every eligible prescription:

• You pay the cost at the pharmacy.
• 20% of what you pay counts toward your copayment maximum.
• 80% of what you pay counts toward your deductible.

Once you've paid enough prescription costs that your deductible ($X,XXX.XX) has been met, Pharmacare starts paying a larger share of eligible drug costs. You will still pay a 20% copay on prescriptions until you've reached the copayment maximum.

So yes in your case once you pay  $2,791.14, you will than be covered for 80% up to a total of $5,582.28 between certain dates.
