I have faced enough problem due to last name.........my wife name was only first name.........so when i fill the application without last name application was not able to validate..........so than i put my name as a last name to my wife then i was able to fulfill the application...........so above advice is best to cover all the future problems.......and wastage of time........
I have a similar issue with just the first name on passport and pr card.
I have got my passport modified and sent an application to cic now to get the pr card modified.
meanwhile, when I went to rent a car I was told you can't get into any legal contract without a second name. though rest everything is fine. did not face any issue even in getting a job.
