On the e-passport, a certain amount of data is there in electronic form in the chip, but it is the information that you see on page 3 of your passport, nothing more, nothing less. The record of when you have gone in and out of Canada or other countries is not in that chip and will not be in that chip, but the basic bio data—date of birth, place of issue of the passport, height and weight—as we have it on page 3 will be there.
