http://laws-lois.justice.gc.ca/eng/regulations/SOR-2002-227/section-183.htmlSorry, I didn't see any references that state that applying for a different status gives you an implied status. There was only a statement by one member who kind of quoted something, without giving a reference for that:
Bottom line:
In previous posts there were no links with this sentence. I really want to see the source. Please, give me the link.
Calling is not an option, as call agents are not qualified at all and they often give opposite answers. Moreover, there is no way to prove that they really said something, if IRCC questions your status.
Now, about people's stories. I totally understand that there might be successful stories, but this is not a proof that these people really had implied status. The reason that people were ok is just someone who is being sponsored under family class cannot be deported (unless there are grounds to reject PR application). So, IRCC preferred to shut eyes to that people being out of status. However, this changes nothing from the legal point of view.

Like we kept saying, Implied Status is applied once a Temporary Resident extends his status prior to last day of his authorized stay and still waiting for the decision of the application. It never said it has to be the same permit. Just his Temporary Resident Status. It may be visitor, student and worker. Status and permits are different things. I don't know why you still don't get it. Please consult a senior member. They might have better references for you but the links I gave you are already understandable.
