What ultimately drives share prices of an ETF? Is it actual trading or only a reflection of the trading of the underlying securities? Or both? It tends to be a bit of both.

He owns this as a sort of core holding for absolute yield, but has taken a big chunk of this and moved it to iShares S&PTSX N.A. Preferred (XPF-T) which he likes because it is 50% US Preferreds and the other half is in Canadian preferreds. The spread between preferred share yields in the US and the 10 year bonds is still extremely high so there is room for that spread to come down.
