depending on your initial application date, you should receive the email to invite you to reschedule.
there is little you can do other than that. don't fall for scams.
I moved to Oct 2025 with Vancouver. I feel they are inviting Sep/Oct 2025 to reschedule thats why there are some slots around this month. You need to keep refreshing non stop for a couple hours in the evening time.
congrats on moving to to Sep 2025. How often did you have to check the website to find the random slots release?
I applied Jan 2024, still confirmed for Jan 2026 and never saw any released slots in my account. And no reschedule email yet.
I heard they no longer release earlier slots so perhaps just wait for email. It's a rumour though but over the past several months with intense checking I have not seen early slots at all so that may be right. Fingers crossed they can expedite the rescheduling.
