When did the Cdn. at Par start?

[NorthernON_MOM]

We did the Canadian at par deal and just got back. We booked in Jan for our March vacation but I was wondering if anyone knows where it started. I know you had to book by Jan. 26, but did it only start in Jan? or Dec.? Nov? thanks.

Happily, we did.!!
