OTTAWA — Canada is about to add another layer of security for travellers who need visas to enter the country — biometric screening.

The Canadian Press has learned that Prime Minister Stephen Harper is expected to announce the new security measures on Thursday.

Biometrics can include unique identifiers such as an iris scan or a fingerprint record.

The procedures are already required for travellers from about two dozen countries — including Afghanistan, Syria and Egypt — but they would now apply to those from almost 150 others.

Canada would join several other countries that require travellers to undergo the biometric tests.

An internal memo obtained by The Canadian Press last year said the government was building an information technology system that could be used for the systematic exchange of biometric data with Britain, Australia and New Zealand.
