I'm also interested in the flexibility that CIC has adopted. Page 2 of your presentation says:
CIC has adopted greater flexibility so that parents and grandparents who wish to visit family in Canada while waiting for their immigration application to be finalized may apply for a multiple-entry visa. This flexibility allows them to enter Canada several times during the period their visa is valid.
Can you comment a little more on this and say what benefits it's going to bring about.
