My chances for Masters in Economics in Canada

Hey guys, I am currently studying economics in Italy at university of bologna and I am considering to apply to canada, my desired universities are Mcgill, Uoft, UBC, UWO, Queens, Mcmaster and University of calgary. My CGPA is 3.3/4 (I slacked in my first year) however my gpa was 3.7 in my second and third year. I have a 160 on my GRE quant section. What are my chances of getting admitted to a masters degree in ecomomics? I saw on these universities website that they emphasize on the last two years or final year of your undergrad is it true ?
