Questions & answers
Using this directory.
How to use the external links and where to verify current information.
Do resource links open in a new tab?
Yes. Each resource card opens its destination in a separate tab so this GTA directory remains available.
Are all listed resources government websites?
Many links lead to government or regulator portals. The directory also includes selected third-party references, which are identified in their card descriptions.
Does GTA control the information on linked sites?
No. Each destination is maintained by its own publisher. Check the destination for current information, requirements and availability.
Does a link or calculator on this page constitute professional advice?
No. This page is a navigation directory. A linked calculator or publication does not account for every fact that may apply to an individual matter.
What should I do if a link has moved or appears out of date?
Use the relevant government or regulator website to locate the current resource. GTA should periodically review these links and descriptions before publication.
