I dont think that's a possibility because that's what it states in the inland guideline:
For the principal applicant and his or her dependent children
Passport
Passport pages showing the following information:
name,
date of birth,
issue and expiry dates,
the stamp made by a Canadian authority showing your most recent entry into Canada.
Format: Photocopies
Immigration document confirming your status in Canada
Examples:
visitor visa,
study permit,
work permit,
temporary resident permit (TRP),
document proving that you have legal status in Canada.
Format: Photocopies
the person needs first to get a status in Canada and then be sponsored inland - once the sponsorship has started the person gets implied status and no longer needs to maintain a legal status in Canada, but it needs to be there in the first place.
At least - that's my understanding of the guideline.
Good luck,
