ADVICE NEEDED: Have I been scammed?

Hey all, I’m going to try to keep this short since I’m sure no one likes to read long posts.

Basically, my friend and I are from Southern Ontario and are moving first year to uOttawa in September. Rez is too expensive so we opted to live off campus, and I posted a Kijiji ad asking for an apartment. Lo and behold, someone with extremely poor English replied with pictures of a pretty nice place with a price of $700

Since the English was terrible, I was obviously sceptical. I talked to this person quite often, and then she even sent me her passport (I didn’t even ask lol). She’s Canadian and white, not sure why she can’t spell or use grammar ...

Anyways, she’s out of province with her sick mother or something, and I live 10 hours away from Ottawa, so I figured I’d give her the $1400 deposit as she kept stressing it was refundable whenever I wanted. We agreed on August 1 as the move in date and I still haven’t gotten the keys. Have I been scammed?

I’ve emailed her a bunch and she only replied once, stating she’s taking care of legal stuff with her lawyer. I’m not sure if I’m overreacting here, or if I’ve made an idiotic mistake.

Please help me, I’m fucking scared guys.
