How did you get your PR? (EE? PNP? famly sponsorship?) Have you landed with your COPR yet?
If not, you CANNOT land with your current COPR (where you are noted as "single"). Send webform to inform IRCC of your new status and amended forms (IMM0008...etc) including your new spouse in it.
She/he will need to go through medical, police and background checks before you get new COPR with her/him.
