What are the conditions for applying for Canadian employer-sponsored immigration?

I have learned from many aspects, and finally I learned from Qiaoshen's overseas service website that the qualifications for applying for the Canadian employer-sponsored immigration program are: the age is below 25-45 (from the date of application documents), and the age can be relaxed by several years under special circumstances; At least a college degree, if not, a professional certificate (such as apprentice, business license, etc.); English, the most basic (ITELS 5. or above); No criminal certificate, the principal applicant and family members over the age of 18; No serious illness; Have more than three to five years working experience; According to the score of the local immigration bureau, standard score must exceed 35, and the higher the score, the greater the confidence.
