The Recording Industry Association of America (RIAA) certified it three-times platinum, for shipments of three million copies across the United States.

[11] Bublé said that during the recording of It's Time he "came into [his] own as a songwriter" and hearing his own song on the radio made him feel "like a true artist.

Timuss sang backing vocals on "Home" and appeared in the music video,[10] which was filmed in the Orpheum Theater in Vancouver, Canada.

I've had the honor of performing "Home" with Michael Bublé on a couple of occasions and can honestly say he is a really great guy, and I think as a writer he's probably pretty excited that it's reached number one, too.

[19] Woodrow Wilkins from All About Jazz commended how It's Time was "relevant to today's audience" and noted that Bublé "delivers [the songs] with the heart and passion that only a person who claims ownership of these titles can muster".

[20] However, Caroline Sullivan of The Guardian didn't appreciate the album's composition of jazz and pop covers, saying that "Sinatra is turning in his grave".

[22] Amy Lichty of the Daily Emerald said that "Bublé's clear voice and smooth rhythms keep the CD moving along", but also noted that he "is simply no match for either Sinatra or Connick"[21] Musicians Arrangements Studios
