| If you got married, you are no longer considered a dependent and you won't be able to keep your PR visa. If you try to land without disclosing the change in your marriage status, you will be held liable for misrepresentation.
Refer to CIC Processing Manual OP02, Section 5.13 regarding who qualifies as a dependent child:
"In order to meet R2(b)(i) of the definition of “dependent child”, a child must be under 22 years of age and not a spouse or common-law partner on the date when the IMM 1344AE is received by CPC-M, and not a spouse or common-law partner when the visa is issued, and when they arrive in Canada.
Not a spouse or common-law partner means that the dependent child must not be married or involved in a common-law relationship. A dependent child who is single, divorced, widowed, or whose marriage has been annulled is not a spouse. Similarly, if the dependent child was involved in a common-law relationship but that relationship no longer exists, they may be considered to meet the definition."
