If you cool air to a temperature comfortably above the dew point, there is absolutely no reason that dehumidification is obligatory. There are two reasons for dehumidification: running the coils at a temperature cargo-culted from a standardized guideline that doesn’t take the local climate into account and running the coils at a temperature such that adequate cooling capacity can be achieved at a low-enough airflow.
At the other end of the spectrum, most radiant cooling systems cannot safely dehumidify.

Seeing as it was -30C a mere 6 months ago, and many Canucks think 15C with sun is a nice temp, comfort comes at close to 20C. Which of course, with the sun pounding on the house, means you need the return air to be 10C or some such.
