Thank you for your answer, but people are considered as "implied status" after submitting the application for the extension of the TRV as seen on the CIC website:
"if your visitor visa expires after you have submitted your application for an extension of your authorization to remain in Canada, you will be considered in status as a temporary resident (visitor) until a decision is made on the application. This is known as implied status."
So, my question is after 1) applied for extension 2) visa expires and waiting for the answer 3) now since I am waiting for the answer I am considered as 'implied status' (until the decision is made on the extension) 4) can my partner sponsor me during this period ?
thank you
