I want to confirm if this is a scam

Someone messaged me out of the blue with the subject line RE ROOM.
He's asking for a place to stay, this is the most recent email he sent me

"sounds good . im willing to pay extra also depending on circumstances.
right now im applying for a visa to ONTARIO and would appreciate some contacts in ontario.
Is it aright If I provide you as a contact in CANADA ?
The supporting document for the visa would state that that I am currently looking for housing in ON, CANADA and would list this snippet of conversation as evidence that i am looking for rooms to rent"

Im pretty sure this is a scam since I never posted an ad about a room to rent. Id just like to know how this type of scam works.

Hi,

The fact that he randomly messaged you about a non-existent room is a good indication that there is something dodgy going on, but it's hard to say exactly what his motives are from the email that you posted.

It's possible that he is just trying to fraudulently obtain a visa, although I doubt that a random email about the possibility of a room would be considered as evidence. The other possibility is that it could be an overpayment scam, he would agree to rent a room from you and pay you a deposit. The payment he sends would be too much and he would either ask you to refund the difference or pay a third party (in reality the scammer using a different name) for something such as visa fees.
