IMO, they should have waited to announce the program. If they had announced it today, and released the portal and full application guide (not copy-pasted) expecting to start accepting applications in 3 weeks, people would be much better prepared and everyone would have had some time to gather "difficult" documents such as medical exams and PCC.
But releasing the application guide the day before the stream opens is just a joke, because even if the stream is "technically" supposed to be open until November 5th, we all know eligible people would want to apply ASAP, and non-eligible and semi-eligible people will panic and try to apply in fear the spots run out. This program has way less requirements than CEC, and after 2020 very few recent graduates have had time to gather 1yr of skilled work experience, or if they had a NOC C or D job, they didn't expect to have a chance to apply like that so many of them didn't bother with IELTS.
These new streams are many people's only hope at getting PR, it's first come, first served so it makes a lot of sense people will rather risk it and apply without certain documents (that we just learned today we needed) than wait and see how the program cap gets fills second by second without being able to do anything.
Yes! But no.
We're not being forced to apply tomorrow or miss out, the problem is not IRCC, it's the number of eligible people eager to apply ASAP.
