The Kindle is well priced because it is really a Trojan horse for Canadian customers.
Sony eBooks are touchscreen which make them full of glare and low contrast.
I live in Canada, and have the same needs as yours, I m comparing Nook WIFI, Kobo WIFI and Bebook Club.
Kobo is a great machine but not sure if is sturdy enough or not, we have no custom fee to pay as a Canadians,
The Nook WIFI is gorgeous too but a little more expensive plus the custom fee.
Personally I leaning towards Kobo in this moment.
