Miraculous wedding venue daughter saw on the inside, Celine Dion's home once (6)

I believe the answer is:
canada
'celine dion's home once' is the definition.
I can't judge whether this defines the answer.
'miraculous wedding venue daughter saw on the inside' is the wordplay.
'miraculous wedding venue' becomes 'cana' (I am not sure about this - if you are sure you should believe this answer much more).
'daughter' becomes 'd' (genealogical abbreviation).
'on the inside' says to take the centre.
The middle of 'saw' is 'a'.
'cana'+'d'+'a'='CANADA'
Can you help me to learn more?
(Other definitions for canada that I've seen before include "- Balsam; - goose" , "Nation in northern North America" , "Second-largest country in the world by area" , "Country with six time zones" , "New World country" .)
