OP is looking at a DL U fare, and for many international routes at certain times of the year, you won't even see a T fare published.
I don't understand what you mean by DL taxes being higher being a topic of discussion around here. Tax breakdowns are freely available and there's no mystery. As to why YQ is higher on one carrier than another, it's really just part of their fare structure.
