I need him to sign a guarantor form for me for leasing an apartment room in Ontario, Canada, but he's away from home for the next 6 hours and I am supposed to drop it off in a few hours. Not a big deal to reschedule but I'd still like to ASAP.

Anyways, am I allowed to send him the scanned version of the document and he sign it using touchscreen on his phone any way we want? For example can he like just draw on it using an app? OR maybe get a picture of his signature and photoshop it on to the form then send it back?

Not sure what's allowed and not allowed, thanks!
