Hi, in Canada a an ESL teacher must:
"Teaching in
Canada: If your primary goal is to teach English to adults in
Canada, generally speaking, the minimum qualification to teach English is a bachelor's degree and a
TESL/
TESOL certificate from a
TESL Ontario or
TESL Canada accredited program. UofT.
I would ask them about the correct NOC.

"NOTE: This is a limited enrolment program. Admission to the TESOL Certificate program is competitive and meeting the minimum academic requirement does not guarantee admission. Admission requirements are subject to change without notice." UofT
In my estimation it is NOC 4031.
But CONTACT U OF T TO MAKE SURE.
