Help with supposide apartment "lease"!

So I talked to my Landlord today.

When I signed my paperwork, my Landlord had me also fill out a sheet that was “About Me,” so it had my contact info, employer, etc. It also had a check box stating how long I was looking to rent for. There were 2 boxes: 6 months or 12 months. I checked 12 months, because that’s at least how long I planned on renting an apartment for. I’m 99% sure that I didn’t sign that paper, I think I just wrote down my information. I don’t think there was even a section for a signature. But even if I did sign it (I never got a copy of it from him), it looked like just a home made contact information sheet that he wanted to have for his filing. Then I signed the official Residential Tenancy Agreement, which doesn’t state any sort of lease on it.

My Landlord said that because I checked 12 months on my “About Me” paper, that means I’m bound to a 12-month lease. But I never signed a paper that stated the address of the apartment, and that I was committing to staying there for 12 months. I may or may not have signed an “About Me” sheet of paper.

And the next day after I had signed the paperwork, my Landlord dropped off photocopies for me. He didn’t include the “About Me” paper. So I figured it was just for his own personal filing.

What do I do now?
