留學一問,多倫多

F5..I believe is grade 11...so you still have a year left, Mcdonald International Academy and Braemar college both sound good, but you may want to consider public or catholic funded schools as well.

About the working permit, it may be quite difficult...many of those visa students simply work for jobs that pay cash (which is illegal, but it's all over the place in Toronto), like restaurants and supermarkets. However, your salary MAY BE below the minimum wage (which a bit under $8CDN/per hour)

Now onto university, it depends heavily on the degree you studying for, but take a typical commerce/business management degree for example, tuition fees are as follows:

Science degrees like Life Science or engineering are more costly..and professional degrees are even beyond that price.

HK $600, 000 is roughly $76 923 CDN...which should be enough for a 4-year degree if living and eating costs are covered. However, like you said, maybe you should consider a part-time job if you want to have some extra money to spend

Some other universities are:
Ryerson University (located in the heart of Toronto, I mean downtown, very closeby U of T)
McMaster University (in Hamilton, I'm estimating a 30-40 minute drive)
York University (in North York, Toronto)
Ontario college of Art and design (Canada's largest city in terms of art and design)
University of Ontario Institute of Technology (newly recognized university)
University of western Ontario (located in London, Ontario, maybe roughly a 2-hour drive from Toronto)
Queens University (in Kingston, Ontario, maybe a bit far, about 3 hours)

You may want to take a look at the website below, it lists quite a number of secondary/high schools as well as universities that are rather well known in the GTA (Greater Toronto Area)

Hope all of this helps

樓上嗰位朋友已經講得好清楚, 不過想提提你; 你所講嗰兩間學校相信係專為外國學生開嘅私校, 相信冇本地人讀, 其實你都可以考慮吓入公立學校, 選擇多而且又可以同本地學生一齊讀.
