Well shiver me timbers, I got this wrong. Special rules do apply
for a pool subpanel. NEC 680.25 states that any
feeders supplying a pool panel must be in conduit, either EMT, PVC,
liquidtight, etc. So, the installers are correct.

680.25 Feeders.
These provisions shall apply to any feeder on the supply side of
panelboards supplying branch circuits for pool equipment covered in
Part II of this article and on the load side of the service equipment
or the source of a separately derived system.
(A) Wiring Methods. Feeders shall be installed in rigid metal conduit,
intermediate metal conduit, liquidtight flexible nonmetallic conduit,
rigid polyvinyl chloride conduit, or reinforced thermosetting resin
conduit. Electrical metallic tubing shall be permitted where installed
on or within a building, and electrical nonmetallic tubing shall be
permitted where installed within a building. Aluminum conduits shall
not be permitted in the pool area where subject to corrosion.

It appears the Ontario Electrical Code does not need separate or
additional conduit if the wire is in "liquidtight flexible nonmetallic
conduit."
The point emphasized here is that outdoor power lines must be buried
(about 20 inches deep.)
