URGENT: written authorization from ircc for accompanying children (8 years and 3 years old)

[powereng1982]

Hello everyone,

I am writing to get some information urgently if I need to apply for written authorization from ircc for accompanying children before we can travel.

We are a family and we will be travelling with following status.

1. Myself = Work permit holder + fully vaccinated
2. Wife = Visitor visa + fully vaccinated
3. Child (8 years old) = Study permit holder + No vaccination
4. Child (3 years old) = Visitor visa + No vaccination

Based on information provided above, please I need to know if my children (both or any) need written uthorization from ircc?

We have already booked flight ticket for the first week of November 2021 and yet I didnot apply for written authorization letter based on following assumptions

1. Parents are fully vaccinated
2. My son (8 years old) is travelling with study permit
3. My son (3 years old) is minor and according to IRCC

Children who are under 5 years of age:
Exempt from pre-entry test
Exempt from arrival test
Exempt from Day-8 test

Should I be allowed to travel with kids? or I should apply for their for their written authorization letter.

Any confirmed information shall be of great help. THANKS
