I will be very honest with you.
The guy who thinks working at Deloitte is an achievement and working at Tim Hortons is embarrassing, was to be rejected undoubtedly.
And I guess I already have had a discussion with you in the past, but you have really serious misconceptions and stubborn views about Canada and it's education and immigration rules.( I am not sure if you are the same guy who called North Indian students to Canada 'villagers' because to my surprise that thread have been deleted now)
Also, if one needs to get some kind of specialization in his/her field, then they go for a Masters and not Diploma.
Don't advise people on Canadian education when you belong to some different field. I am a licensed academic counselor in Canada and a PhD Scholar here.
I always advise students to go for a Masters rather than a diploma if they can, but that wont make me say that PG Diplomas are bad. They are good. Make yourself worth them.
Also, the day you will value each and every person on this planet, you will get good things in your life.
