Don’t know where you are in Canada (which I’m assuming based on “Social Insurance Number” and “Prov.” fields in the form), but at least here in BC much of what they’re asking for here is illegal to even request in the first place.

Your Drivers License, and banking info are all personal private information which are covered by the Personal Information Protection Act (PIPA). This guidance document from the Office of the Information and Privacy Commissioner of BC outlines what a perspective landlord can ask for, and what they can’t.

This is either a scam, or a really shitty landlord. Either way, don’t deal with them. You can open a complaint with the OIPC if you want (probably most useful if you’re sure they’re legit; not too useful if it’s a scam).
