Will you help us find a link for jobs there?
I am working as a security supervisor in Dubai since 2019, I am trying to find a way but never found anything solid yet.
To get a closed work permit you have to find a job and an employer who is willing to apply for LMIA. (cost the employer 1000 Cnd and time to apply and get approval)
The LMIA will show that they cannot find anyone in Canada that has your specific experience, skill and education to fit that position. Unless your security supervisor skill is very specific to a field that's hard to find, I do not see that as anything easy.
Then with LMIA, you can apply for a work permit to work for that employer.
So yes, you are correct in your original post. It's very hard to geta a job in canda as a foreigner.
