Some parents choose to send children to study in Canada as international students because the hardship is much less than in some Asian countries such as China and Korea.

Suggestion is to plan early. Do not wait until the child is in Grade 12. This is especially true for kids in China and Korea, where the mother tongue is not English. If kids are here in Canada in Grade 8 or 9, usually it takes about 6 months for them to be adapt to the class. However, if they come at grade 10 or even 11, it is usually better that they take some English preparation in their mother country. For example, to get 6.5 in each subjects of IELTS.
