I am wondering if it is better to install the ballast on the canopy or under the tank? If I install it on the canopy, it should be easier to remove the canopy. What are the pros and cons?
not sure I understand your Q. What kind of lights are you installing? Most ballasts dont need a fan to keep cool as long as they have adequate airflow around them.
poppin-fresh nailed it, as long as they're not getting wet or boxed in too much, they'll be fine. Most do not require any type of active cooling, but you don't want to pack it in.

I think he means INSIDE the canopy. So the fans can cool the ballast. I have mine ON TOP of the canopy. Not inside. They run plenty cool. I run fans on the Metal halide bulb only.

I did put a few metal washers bewteen the ballast and wood so air would circulate between the two. I used stainless bolts and nuts so I could get them apart later.
