Hey,

If you want to go abroad for Undergraduate studies the  it doesn't really matter which school you went. If you have enough skills. But if you are going to appear for any entrance exam in India like JEE,then I suggest you should go to dummy school as you won't have much workload and you will have enough time to study for JEE.

But also make sure you study for the entrace that you need to give to get admitted in your choice of Canadian university.
