Called by phone to talk to a representative. She said the service they usually ship with depends on the weight of the package. The lighter packages tend to be shipped by Canada Post while the heavier ones they use Purolator & Cornerstone. She also told me if Canada Post does go on strike then Purolator will probably take them over.
Anyway I bit the bullet & went ahead with the order. We'll see how it goes. Fingaz crossed.
You should get it very soon unless its a preorder...likely you will avoid any strike.
