When did you complete your initial landing given you need to reside in Canada for 730 days in the 5 years from initial landing. If you landed for example Nov/Dec 2016 then sure arriving May 2019 not a problem but you would need to stay in Canada for a while to meet your 730 day residency obligation before applying to renew your PR card next time.
PR card validity is irrelevant to meeting the residency obligation by the way.
