Does my bathroom need to have a fan?

I'm in Nova Scotia if that makes a difference in the building code requirements.
My house has two bathrooms. The upstairs bathroom has a fan. Downstairs, no fan. The downstairs bathroom is on a floor that is half below and half above grade - the bathroom is in the front of the house and is about 60% below grade. It has a normal sized window (identical to upstairs) and it's hard to tell how low the room is without looking out the window.
Every time someone showers in the room, the walls (and window, and mirrors) get a lot of condensation on them. You can see the moisture drips on the walls and these drip patterns, if you scrub at them with water, leave an orange residue. I'm sure this is mildew from too much moisture.
It's always kind of bothered me that there is no fan in the bathroom. I know I could just open the window every time I shower, but it gets cold cold cold in the winter. Plus, the level of the room means it would be really easy to climb in/out of the window, so I get a little paranoid doing that when I'm home alone.
The main question is - should this bathroom technically have a fan? I just can't understand why there isn't one. My parents had the house built so it's not a renovation done incorrectly. I think installing a fan would be difficult as there is no simple way (that I can see) to vent the fan exhaust as the outside wall is covered in brick.
If a fan isn't a requirement, why isn't it? What can I do (short of opening the window every time, which is only minimally helpful) to reduce the amount of moisture that accumulates on the walls? Special paint?
