The whitetail draw is for Canadian residents outside of the province. As remyltr said, you just have to purchase.
I was drawn last year for antlerless elk and the previous year for antlerless moose so I really didn't expect to be drawn for those species this year and ... I was right.
But it's mule deer year for me in Zone 7, antlerless in E and either ### in W. I must get on my bike and get down there and start looking around.
