I’m sorry but I don’t think you will manage to get admission in decent Canadian universities with your board percentage. The grades and academic excellence required by Canadian universities are very high so your chances of getting in are very slim. 

hey kunwar...the Academic Requirements of canada : Applicants for a postgraduate program must havegraduated from a University or College. 1st or 2nd class degree results required. Second class degree result must have a minimum overall average of 55% for Business programs and 60% for all other streams.Nov 14, 2018

Hey Kunwar,

With only 49.4%, you wont be able to get into any university in canada as all the universities have higher requiremnets than this but you still have an option to go to canada. what you can is to opt for college rather than a university or maybe something with foundational program. This might help you to neglect your low marks in class 12 and you will be still able to get a diploma in canada.

Hello Kunwar

I am afraid not, because Canada looks at nothing less than 75% overall and 75% in Maths. So at least for all the top notch colleges it would be hard to get through if one does not score required percentage..

However, there is a way out. Incase one does not fulfill the eligibility criteria, one can chose diploma/pathway program to enter.

Idea of the pathway program is that one gets to study foundation program and does not get admission in degree program directly. However, after completing one year of foundation program, one can tranfer the credits into the degree program.
