Unless the fan is running constantly the ambient temp in the attic will be the temp of the duct.

Just an update on this as I went up in the attic this weekend to get some recessed lighting installed. I checked the bathroom exhaust duct work, and I could feel some bits of ice had formed in that dip in the duct work from the bathroom fan to the roof vent. I don’t know if it means much. It didn’t seem like *a lot*, but enough that it would make a mess on the ceiling if it melted.
And on the topic of lighting and wiring - anybody familiar with the CEC enough to say whether a junction box have something like a medicine cabinet installed over top of it, or do they need to be readily accessible? The box used to have a vanity light installed on it, but our medicine cabinet we picked out is tall and would cover it up. Conversely: we could cut the drywall and move the box further up the wall if that makes it okay.
