I rented an apartment before and the superintendent asked to register in Hydro, but when I came to Hydro, they said the superintendent had already registered me. Never trust the superintendent, they just know a little thing and just remember to bill you.
I think the bill includes the interest of the fee you should pay for the first 7 days. I read a story that a teenager rent a Video for $1/day, but the store said he lost it and didn't pay for it, after one year, the bill became a big bill with hundreds of dollars. He went to the court but he couldn't provide the proof that he returned the video so he had to pay the bill, otherwise he can not get the loan when he buys a used car.
Maybe you can contact with Hydro to find who registered you and when.
