Although it is a so-called subordinate college in western Ontario, both King's College, Huron College and Brescher Women's College are adjacent to the "main campus". Our professors, such as my professor of environmental science, have three classes a week, one large class in the main campus and two small classes in Huron College. The teaching resources are completely shared, and the diplomas are exactly the same. From the school center to Huron College is closer than to the teaching building of educational facilities, so this nominal "campus" is actually very light from the perspective of our school.
I don't know who you mean by "everyone says the teaching quality in branch schools is average" Do these "people" understand the undergraduate system of Canadian universities? The undergraduate education of all universities in Canada is very unified, and they are all public universities (that is to say, there is no "diploma workshop", so please go all the way south if you want to go to the pheasant), and the funds are allocated by the provincial education departments. If the teaching quality is not up to standard, there will be no funds. In other words, whether it is a large medical university or a basic university specializing in undergraduate education in Canada, the undergraduate courses they offer are almost the same. Of course, postgraduate doctoral students are another matter. Therefore, it is rather boring for Canadian undergraduates to discuss "teaching quality" and "teacher level".
Economics belongs to social science in the west, which is the largest department in the west, and the Social Science Center (SSC) is in the center of the school, so even if you come to Huron or King's College, many of your classes may be in this SSC. If you decide on this 2+2 project, you can come to Huron. Huron has a history of 160 years. Huron College came first, then Western College, so in terms of qualifications, Western Ontario is a branch school.
I hope I can help you! Good luck!
