Unfortunately, the ranking system is ageist and considers youth to be a very important factor. So by that logic, a 23-year-old with a Bachelor's degree and one year of work experience is deemed "more valuable" than a 40-year-old with a Masters or PhD and 15 years of work experience. Very strange but I am sure Canada has some very good reasons for seeking a younger, more fertile immigrant populationThere is a critical flaw in your logic in the last statement. You are assuming that candidates with scores below 420 are lower quality. They could be just older.
