On March 18 2015, Madonna’s Rebel Heart album debuted on Billboard’s Canadian Top Albums chart at #1.
All seven of Madonna’s studio albums released since Nielsen SoundScan began monitoring album sales in Canada in 1996 have entered the Canadian chart at #1, as did her 2009 hits collection, Celebration.
In contrast to Billboard’s Top 200 in the U.S., where Rebel Heart entered at #2 before falling to #21 the following week, sales remained relatively steady in Canada, with the album dipping only one position to #2 in its second week.
Interestingly, the album that blocked Rebel Heart from reaching the top spot in the U.S. (the Empire: Season 1 soundtrack) charted for only one week in Canada, peaking at #25.
Today In Madonna History 
I think the song leaks then Madonna releasing the partial album early on iTunes before Christmas really hurt album sales in the US.
Well the leaks certainly didn’t help the album in any country. It would be difficult to gage the overall effect of the pre-sale before Christmas, although its sales were applied to first week sales so it shouldn’t have had a negative effect on its initial chart placement.
Agreed with Warren and Justin! Rebel Heart is Madonna’s most underrated album and overlooked masterpiece! Love Madonna!
