这事儿得回到原点，研究移民局自己发布的GUIDE
在担保资格申请的Guide里关于担保资格状态，有下面一段话：
11. Your situation over the last 12 months
In the table in question 11, complete the sections (A, B and C) which apply to your situation during the
12 months preceding the date of your application. If your situation changed during that period, in the
Period I column, enter information on the most recent period and, in the next columns, enter
information on the previous period(s), which make(s) up the rest of the 12 months preceding your
application.
可以理解成为：
经济能力只看交申请之前的12个月，不管以后如何。
下面这段话是在担保资格申请的Guide里的唯一涉及到有孩子出生的部分：
if, following the submission of your application, there are any changes to your family status such as
marriage, divorce, births, deaths, your address, telephone or fax number, or any other important information.
When advising the office of such changes, you must clearly state your file number, which will be found at
the top of any correspondence we will send you to acknowledge the receipt of your application.
可以理解成为：
担保资格申请期间若有变化及时报告，默认可以理解为，担保资格申请过程结束后不必报告。
关于撤销担保里面有关签证签发的内容：
If you change your mind about sponsoring your parents, grandparents, adopted children or other relatives,
you must write a letter to the Case Processing Centre in Mississauga before they are issued permanent
resident visas (see What happens next for information on the application process).
Once permanent resident visas are issued, the promise you, and if applicable, your co-signer, made to
support your family is valid for the term of your undertaking.
明确说明：一旦签证发出，你的担保就生效。
逻辑上来说，担保一旦生效，就不是你有无担保资格的问题，而是是否撤销担保的问题。
按照以上元素综合理解，楼主的报告是多此一举，与诚实与否无关，产生的效果是让移民局官人误认为你对自己的担保能力缺乏自信自己拿不准，要官方帮你重新审核一下担保资格看看能不能养活得起被担保人。
个人评价：楼主这不是诚实，是二。
楼上那个趁机歪楼的什么“原罪”什么“党”的那个，你更二。
