Apartment contract expiration without moving out - can I stay?

So our lease expired on 3 Dec and our landlord didn’t get in touch to renew it or to ask us to move out. What does that mean going forward?

I assume we can just stay until we decide to move out as long as we keep paying rent every month because that’s what’s happen in other countries.

I wouldn’t assume that.

I would get in contact with the landlord ASAP.
