just wanted to add this important info:
how you request authorization from IRCC is not the same for everyone; according to the IRCC website:
Step 5: Request written authorization to travel
Once you have a copy of the completed and signed IMM 0006... use it as evidence of your relationship with your family member and request a written authorization from us. You need written authorization whether you’re travelling from the US or any other country.
How you request a written authorization depends on whether or not you already have a valid travel document (visitor visa or eTA).
When you click the link "find out how to request authorization," it takes you to another heading (on the same page you were already on)
the subheadings here are:
- If you have a valid visitor visa or an application in progress
- If you need a visitor visa but haven’t applied for one yet
- If you have an eTA or need one to travel
- If you don’t need a visitor visa or eTA (for example, US citizen)
for people in cases 1. or 2. it takes you to the page "Coronavirus disease... :
Visitor visa applications" and in one of those cases it tells you to email
IRCC.COVID-TravelExemptions... [at] cic.gc.ca
for people in case 3. it tells you to visit this webpage:
