I've just received a conditional approval for NEXUS and tried to schedule an interview on-line. I live near Ottawa, so YOW is the logical centre to use, but the first available interview is July 12. I am (unfortunately) at YYZ quite a lot, so I tried that centre next. There are no interviews available period at YYZ.

Is this normal? Can I just drop by the YOW centre and be interviewed? Or am I going to have to wait until July 12?

Thanks
