This is for Canadian students who have studied abroad. It is mentioned in better detail in the program admission requirements
International Credit Evaluation
Canadian citizens or permanent residents with international education are required to provide a WES or ICAS evaluation.
As for the total fees, the fees mentioned in the program page is all-inclusive. The page
https://humber.ca/admissions/fees/tuition-expenses.html shows the break up of the page.
I have already got the offer letter in my hand which is why I am telling you that it is not required to get a WES or ICAS evaluation. Regarding fees I have not paid since I am waiting on another college so I cannot confirm but the 16, 531 figure should be accurate.
Also, it is Mandatory Non-tuition fees. This means that it is not part of the tuition but it is mandatory for you to pay for it. There is no such thing as non-mandatory fees.
