Sorry not OP.
Written on official website, scroll down to check highlighted validity fact...
https://www.cgitoronto.gov.in/page/police-clearance/#:~:text=The%20PCC%20is%20valid%20for,there%20is%20no%20emergency%20PCC.
The email you got saying we are about to finalize your application....
In the end should be signed with the code name of the officer along with the VO ( atleast thats what mine mentioned)...
Since you mentioned you have been awarded the certificate so it is what you mention.
Level of education is the highest education you have till date....
So for work purpose, right?
In this case you have to research for evaluation of teacher's board. WES is for immigration, teacher's board evaluate for assessment. Research about board in your province, Google foreign teacher evaluation and you could get results.
The process is to undergo treatment in Canada.
Validity of medicals have nothing to do with surveillance.
No need to give medicals again.
Form needs to be show at port.
Read the letter again what it says....
I think then it would be a problem, as you are not paid as per the requirements... It could be a problem while applying PR satisfying the officer that you are paid less than the requirement......
