That's your personal choice, but going through this anxiety and process twice is not something everyone is comfortable with.
Flexibility of moving alone initially and calling family later is possible even when PR application for the whole family is processed together.
And who knows what policy change might Canada bring in later for spousal application especially the ones where one initially declared spouse as non-accompanying! But to each his own. End of the day it's a personal decision. Goodluck either ways!
Sir, please do not spread the scare / uncertainty by using something like "who knows".
No country that is welcoming Immigrants to fill up their manpower requirements and keep their economies rolling, would think of keeping families apart, that way it would be counter-productive for them. Understand this that they are asking whether your spouse will accompany you or not only to figure out what choice depending on your personal situation, are you going to make when you are making the application (different people in different situations will make different choices - applicants in EE come from world over, not a few select countries). Their objective is not to get one person in Canada who has declared spouse as "Non Accompanying" and then make life difficult for them by making spousal application hard / impossible so that couples / families are separated.
I had already said that the process might be different / slightly lengthy and all, consuming some more time or money, but on the long run (when you are intending to permanently settle in another country for your betterment), it shouldn't matter. Think about it.
On a lighter note (no offence), your name has the word hope, be like one!!
