The updated Nexus 7 has already started shipping early in the US, but our kindly neighbors to the north haven't seen a mass influx of Nexus tablets yet. There is at least a trickle today as Staples, Best Buy, and Future Shop are beginning to show availability.

Staples is still selling orders online with 1-day shipping. Most stores are also showing it as in stock. Best Buy is sold out online, but a few stores still have units available for pickup. Future Shop is also cleaned out online, but offers the new Nexus 7 at a few retail locations. The price for the 16GB tablet at all stores is $249.99 in Canadian money.

The 32GB version has yet to break cover, but if you're desperate to get your paws on the new Nexus 7, you might want to step on it before everyone is sold out.
