Hi,
There are two options -

Many institutions conduct their own entrance exam.

There are only two reputed Canadian universities, who can offer you MBA with 15 years of education (10+2+ 3 years UG)
1-Royal Road University
2- NYIT
But, both of them are a bit expensive universities.
Never go for Vancouver Island University and Thompson River University, they will also offer you MBA, but these are one of the worst colleges you may find in Canada.
