It would be better if you already have 730 days in Canada before you apply to renew but as a new PR, you meet the residency requirements as long as you still could have 730 days in Canada by your 5 year PR anniversary. You haven't been outside Canada for 1095 days or more since you landed and you may renew your PR card up to 6 months before it expires. You are not breaking any rules if you do.
