Ancestry.ca is offering a "weekend special" of free access to its online databases containing 30 million Canadian birth, marriage and death records. You can start at http://www.ancestry.ca/cdnbmd.
Notice the fine print at the bottom of the page: "Free until January 27, 2014, 11:59p.m. (ET). To view these records you will need to register for free with Ancestry.ca with your name and email address. Once you have registered we will then send you a user name and password to access the records. If you haven’t already, you will be prompted to register once you start trying to search and view the records. After January 27, 2014, you will only be able to view these records using an Ancestry.ca paid membership."
