i had the same issue. People cancel all the time but unless you're constantly refreshing the page, you'll never get the dates you want because the way the website works is that the next person who signs up will automatically see the first available slot, which is the cancelled one.
Instead of checking myself all day, I wrote a program that checks every 2 minutes and texts me when a slot on a specific day opened up. Once i set it up, took less than a week and I was able to get interviews at YYZ for both wife and son on the day I wanted, within 30 minutes of each other.
PM me if you have specific dates in mind and want me to set it up to alert you.
That's kind of you offering to help.
But believe it or not I found an open slot for today the 26th at 10:30am.
I applied for GE vs Nexus on erev Y"K as the slots for the nexus enrollment center(In YYZ) was backed up till October 16th, having something(GE) is better then nothing as I'm only in Toronto for Y"T.
Little did i know I would not be conditionally approved until a day before Suckos so flying out of jfk for a few dollars more was a bust vs lga for $99, hoping I would be conditionally approved and take the interview @jfk, but being that all that went south I looked periodically at the nexus enrollment center availibilty to see if anything opened and to my surprise I saw before yt that today morning was available, so took the 10:30am appointment and came at 11am and was in and out within 5 minutes, the whole interview is to be fingerprinted.
Was a bust that I didnt apply for nexus if I was already going to yyz for the interview,the officers were also surprised why book an appointment for GE and pay $100 while Nexus includes the whole shebang for $50..
Ah gitten moed.
And yes was approved for GE,now it's time to sign the family up for Nexus.(Under 18 is free)
