Apparently, you are not a citizen of Canada already. It would take several years to get citizenship, IF you qualified to legally immigrate and obtained PR (legal permanent resident status). On top of spending a year or more to get approval to immigrate & obtain immigration visa, settling in Canada, etc. you must actually reside in British Columbia, paying provincial taxes, for at least a year before you qualify as a provincial "resident" for the purpose of subsidized tuition.
How many years are going to postpone college in some crazy attempt to immigrate, and fulfill provincial residency requirements, before you apply for admission? Canadian citizenship is not enough to qualify for "resident" tuition breaks. Same in US - you must actually reside in the state & have paid state income & other taxes before you might qualify for the taxpayer-paid tuition subsidy.
