Like many national statistical organizations, Statistics Canada (StatCan) is facing increasing national and international demands from researchers for access to detailed microdata. StatCan has recently put in place a new service that will improve access while at the same time protecting the confidentiality of the various data sets. The Real Time Remote Access (RTRA) system is an on-line remote access facility that allows users to create tables, more or less in real time, using microdata or lightly masked microdata sets kept in a central and secure location. There are many challenges in the development of an on-line remote access tool, particularly regarding how to maintain confidentiality knowing the various output products released with their different disclosure rules. The presentation will provide an overview of the development and processes of the RTRA, the challenges of creating another mode of access in a tight budget environment and the methodological options for disclosure control.
