Here is a situation,

i have been issued Permanent residence VISA on the feb 1st week of 2007, while i was still out of canada, but my legal status is changed on March last week of 2007 from single to married,and am suppose to enter canada on the first week of april but i dont have my marriage certificate yet becoz its still has to undergo authentication from the Ministry of foreign affairs.am employed in canada from the sep 2004 and am living there eversince until i exited from canada on the first week of march i.e, after i got my permanent residence visa being mailed to canada. what i want to know now is that do i have to declare my change of status or i can do so after i get into canada?even if i choose to declare on the POE i dont have any documentary evidence that i can show to prove my status change. i would welcome some precise answers which can really help.thank you.
