While there is no news as yet, the Parliament of Canada web site page for "Bill C-24" and more specifically
the page for Coming into Force information, was updated again as of yesterday, which indicates it is indeed updated at least weekly. Thus, this site seems the best source to follow beyond watching for news of the coming into force date in the CIC newsroom or in the major media.
I expect CIC to publish/post the Coming into Force information within a day of the Governor in Council's order fixing the date, but there is
no guarantee CIC will do that. Similarly, I expect a major media story reporting this information within a day of the order, but there is no guarantee of that either and even if it is published it may not be high profile enough to be readily noticed.
Thus, while those sources (CIC and the major media) should publicize the coming into force date almost immediately, the best backup is the Parliament of Canada site,
the page for Coming into Force information for Bill C-24, which at minimum should post the information within a week of the order.
Of course, there is no guarantee that the date the order is made will be more than a day or so prior to the date fixed as the coming-into-force date for section 3 of the
SCCA (amending section 5(1) of the
Citizenship Act, the provisions governing qualifications for the grant of citizenship). My best guess is that the order will precede the date fixed by at least a week or more, which could still mean there is minimal notice. If the date of the order precedes the date fixed by more than a week (I tend to think it will, but by how much is no more than a blind guess), even if CIC does not publicize this information right away, at the least
the page for Coming into Force information for Bill C-24 will give some advance notice.
Note: this has been the case all along, but having anticipated minimal advance notice it was not worth closely monitoring sites like the Parliament of Canada's page for the coming into force information . . . until now. Now because the coming into force of the remaining provisions in the
SCCA is imminent: the Governor in Council's order could be made virtually any day now.
Now it is worth watching such sites closely.
