If you want to immigrate look at Express Entry based on your age, skills, education, language and funds.
If you want a job apply for jobs on Canadian job sites like Indeed. You need a job offer and your employer needs to file for and pay $1k for a LMIA. The LMIA shows that no Canadian or PR could be hired, only you. Then with LMIA, you apply for a closed work permit. For the permit, you show that you are experienced to do the job. Depending on the job requirements, you may need IELTS for language and ECA for education. Few employers go through the process. Research to see if your job needs a license too.
