I don't remember sorry but I did send through my NOA couple of weeks ago. Also no where on the Immigration website NOA is mentioned as a requirement.
As per IRCC official website:
How do I apply for a super visa?
To apply for a super visa, you need to submit an application to a visa office and provide
- a letter of invitation written and signed by your child or grandchild promising financial support for the entire duration of your stay in Canada.
- You must also include your host child or host grandchild’s family composition (dependents, including spouse, children or other relatives that are financially dependent on your host child or host grandchild).
- one of the following documents to prove that your child or grandchild meets the low income cut-off (LICO)minimum (The Canadian or permanent resident spouse or common-law partner of your child or grandchild may co-sign the invitation letter to meet the LICO minimum):
- The most recent copy of their federal income tax notice of assessment. If your child or grandchild does not have a paper copy of their notice of assessment, they can view (and print) their tax returns as well as other personal tax information using the Canada Revenue Agency’s My Account online service. To register or login, visit My Account.
- The most recent copy of the child or grandchild’s T4 or T1.
- An original letter from child’s or grandchild’s employer stating their job title, job description and salary.
- The child or grandchild’s employment insurance benefit statements, including
- a letter from an accountant confirming annual income, if self-employed
- proof of other sources of income (for example, pension statement, investments)
It clearly states ONE of the following and I provided last 3 paystubs, Very detailed letter from my employer yet IRCC refused. If NOA is the most important document then they need to mention it on the website.
