Ancestry free passenger list database not so "free"
Apparently the Canada Day free access to the database The Canadian Passenger Lists Collection 1865-1935 only works like Ancestry’s regular free 14-day trial - that is, you need to register and sign in with a credit card. The payments start after the 14-day trial period.
On the Ancestry.ca website you will see the “free” offer in the middle on the right side. The small print on the next linked page explains the process involved.
Sorry for the misinformation. I thought that they would just offer the one database without restrictions.
