A) The public consultations are not regarding the bill itself but regarding the regulations that are implemented after. Something on the level "How should we design the forms" or "Which proof of language should we accept" etc. Notice, for example, that the law only says you need to demonstrate language skills. The law does not specify HOW they are to be demonstrated. Regulations do that. Note: I'm not saying that they will discuss proof of language details, I was just giving an example.
B) It wouldn't be very helpful to try to read something out of past consultations. They are each so different that comparisons are hard to be made.
C) No, unless you are a legal expert or are particularly opinionated regarding government forms
I would encourage everyone to ignore this CIC link to the announcement regarding regulations. It is a completely formal thing that is of no particular information to us.
