A pop blast from the recent past knocked the Black Eyed Peas from their seven-week reign atop the Canadian album charts.

Hilary Duff's new album "Most Wanted," a collection of her biggest hits and some new remixes, debuted at No. 1 this week with just under 32,000 copies sold, giving the singer her third No. 1 debut in this country.

Duff also occupied the No. 1 spot south of the border, selling 208,000 copies of "Most Wanted" in the U.S., according to Billboard.com.

Back in Canada, The Black Eyed Peas didn't give up the top slot without a fight. Sales of "Monkey Business" rose this week to just under 16,000, up from last week's 14,000, according to Nielsen SoundScan. That was enough to keep the album safely in second place.

Further down the charts, Green Day's "American Idiot" (11,000) and The Killers' "Hot Fuss" held steady at No. 3 and No. 4, respectively. This left the No. 5 spot to Coldplay's "X&Y", which dropped from last week's perch at No. 2.

Also new to the charts this week were The Trews, who debuted at No. 6 with their sophomore release "Den of Thieves."

Jack Johnson's "In Between Dreams" dropped two to No. 7, while Mariah Carey's "The Emancipation of Mimi" and Gwen Stefani's "Love.Angel.Music.Baby" stayed at No. 8 and No. 9. Kelly Clarkson rounded out the top ten with "Breakaway."

Other notable debuts this week included the "Just The Hits" collection at No. 15, Brad Paisley's country album "Time Well Wasted" at No. 18, and Burlington, Ont. band Silverstein's "Discovering The Waterfront" at No. 23.

On U.S. charts, Paisley debuted at No. 2. The Nashville crooner was followed by Mariah Carey in third, "NOW 19" compilation in fourth, and new entry 311's "Don't' Tread on Me" in fifth.
