When renting, you have to give 60 days notice. If you want that in a contract, great. The tough part is enforcing it in the end. If you get a deadbeat room mate who is late or doesn't pay the rent, good luck evicting them.
And good luck trying to get money owed after they leave.

I would ask for the following.

Security deposit of atleast 1 months rent. Not acting as first and last, but a security deposit to cover damage to the unit should it occur.

First months rent in advance.

I wouldn't complicate things with asking for rent and bills. I would overestimate your monthly costs for hydro, water, etc. and make 1 total for the month for rent.

You are now becoming a landlord. You won't find a person to do what your sister did unless you get them to sign a contract for renting for 1 year or longer. But that contract is still binding even if you find that special one, get married have kids and want to move on with your life. You can't boot them out. And you have to continue living there.

Trying getting a roommate that is a professional and makes a minimum of $60k a year. Ok $45.
