Here are a few things that you should be aware of when scheduling an appointment so that you don't need to learn the hard way as I did.

1. The earliest day you can schedule your appointment is for the next day; once past midnight, the schedule for that day would no longer be accessible.
2. You cannot re-schedule your appointment online if it is less than 24 hours ahead; you have to call to talk to someone in person.
3. No one is answering calls for the weekend after 5pm Friday, even though the enrollment centre is open for interviews.
4. For a family, everyone must be booked on the same day, not necessary the same time.

In another words, if you book anything after 5pm Friday for an appointment less than 24 hours ahead, there is no chance for a re-schedule. Consider it final as there is no option online to re-schedule and there is no one to talk to. So be careful if you see an opening slot and you are booking for multiple persons.

For my story, my family of 4 applied on May 26 and got approved late Saturday evening, Aug 6. Checked the schedule and saw an opening in Fort Erie on Aug 7 (Sunday). I thought that would be good as there was trip coming up in mid-August. I scheduled my appointment and proceeded to schedule for the rest of family...... and discovered that it was past midnight, and Aug 7 schedule was no long accessible! I could only book them on another day.

And I was stuck, no way to re-schedule my appointment, and I found that no one would be answering call for the whole weekend, and I didn't want a "no show" (not sure if it would cause unnecessary delay or complication). I ended up driving all the way to Fort Erie to try my luck....... and no luck as they would not take my family which was scheduled on another day.
