California rockers Linkin Park made a piercing debut on the Canadian album charts this week.

Their third studio disc, "Minutes to Midnight," buoyed by the hit single "What I've Done," blasted to No. 1 with over 50,000 copies in sales, according to Nielsen SoundScan data.

It marks the second best debut of the year (Avril Lavigne's "The Best Damn Thing" still holds the record with 63,000), and it also marks the first time Linkin Park has hit the top spot here.

They also grabbed the No. 1 spot south of the border, selling a whopping 623,000 copies of "Minutes to Midnight" there, making it the biggest debut of '07 in the U.S.

Back in Canada, Michael Buble's "Call Me Irresponsible" fell to No. 2, Claude Dubois' "Duos Dubois" slipped to No. 3, and Avril Lavigne occupied the No. 4 position.

Megadeth's "United Abominations" had the second best debut of the week at No. 5, Feist's "The Reminder" dropped two positions to No. 6, and Rufus Wainwright's "Release the Stars" spent its first week at No. 7.

Isabelle Boulay's "De Retour a la Source" dropped three rungs to No. 8, Wilco's "Sky Blue Sky" came in at No. 9, and Pink Martini's "Hey Eugene!" rounded out the top 10 at No. 10.

Other notable debuts included the compilation "Punch Much" at No. 21, the "Shrek the Third" soundtrack at No. 22, Gretchen Wilson's "One of the Boys" at No. 32, Dolores O'Riordan's "Are You Listening?" at No. 35, and "Reggae 2007" at No. 44.

In the U.S., Tank's "Sex, Love & Pain" placed second, followed by Michael Buble in third, Wilco in fourth, and Gretchen Wilson in fifth.
