This current Immigration system is the best in the world and still gets better and more competitive every year.
The requirements are becoming more stringent every year as CIC is starting to know how to get the best economic migrants out there.
This plan was structured by conservatives before the Trudeau government. I talked with a lot of conservative Canadians here and their main issue with Immigration are the people who do not contribute to the economy but rather take advantage of it.
This will stay true even after the elections, especially for conservatives who will hold office as those officials tend to be more educated and non-xenophobic.
Conservatives will not shut down the EE system if they get elected, but instead will ensure that the score remains high which will lead to better, more qualified, and English proficient migrants.
The main goal of EE, when introduced, was to get to the stage it is now.. not to remain in the beta stage that it was for the past years.
Just my 2 cents.
