I've had this cover for mine almost since the thing came out and it's freaking incredible. I never expected it to last so long without any wear at all. It has the auto sleep/wake function you're looking for and the footprint around the edge of the tablet is super minimal. Recommend it 100%.

Mine is very similar (http://www.amazon.com/gp/product/B009RZPH1G/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1) I love this case, it looks great, feels sturdy and the three different angles to prop the tablet are a great feature.

I'm in Canada too. I ordered the iBlason case and it was worth every penny.
