Misrepresentation help for PR - sibling not mentioned

[rosewater33]

hi all,

I applied my study permit without including my siblings in the form. Then my sister also came to Canada in study permit without keeping my name.

Now we both are in Canada in work permit . I will be applying for my PR soon.
can i now include my sister name and have a letter of explanation when applying for pr? Please give me advice. Thank you
