Biometrics Locations Souther Ontario Recomendations?

[US2CanApp]

Spousal sponsorship. Are the appointments for biometrics actualy done around the appointment time? I have heard some security guards at the passport offices are still making people with appointments stand in line and all an apointment is really for just guarantees that you will be seen that day, sometime.

Any comments, or recommendations on what office to go to for biometrics between Toronto and London areas?

Thanks.
