Yeap I got this booklet which gave general guidance.
But as per IRCC guidelines, officially any CoPR issued after 18 March submit allowed to travel.
This 100% sure. I am surprised you have never heard about this as everyone is talking about this.
Please go and check on ircc website.
Personally I will book my ticket through a etihad as you can postpone your flight for free (I live in Sharjah).
Then my agent told me that they have a new process where it is not requested to send a webform “ready to travel” anymore, but rather you should use the arrivecan app to inform them that you are coming and to fill your flight detail.
I have 5 kids and my wife so I am very careful and want to go to the airport only if I am sure I can travel
