What Canadian cabinet members are expected to do

[hazard]

I don't think the Netherlands does that publicly. On the other hand, Prinsjesdag (Prince's Day/Little Prince's Day) is the yearly budget reveal on the third Tuesday of September and that one is always fronted by a speech by the King (the 'Troonrede', literally the 'Speech from the Throne') about what the government intends to do the next budgetary year. It's pretty similar to the Queen's speech opening a Parliamentary session in Great Britain, including that the monarch doesn't have a whole lot to say themselves and is largely a mouthpiece of the current administration.
