WES has free equivalency tool: https://applications.wes.org/ca/degree-equivalency-tool/
Most of the time what you get in this tool is the same result they will give you.
If the equivalent is only 2 years, I suggest you try ICES or IQAS because most of the people I know who got 2 yrs equivalent had theirs reassessed from ICES or IQAS and they got a 3 yrs equivalent.
The only advantage of WES I guess is that they process the ECA much faster compared to the other assessing bodies.
I tried the tool and the equivalent is 2years. What will happen if it only equals to 2 years?
