Hi Parth,
Oshawa has one campus of UOIT that offers MBA. UOIT is one of the first universities in Canada to offer this as a concentration at the MBA level. For students with at least two years of relevant work experience, the MBA at UOIT builds on their employment experiences and can be completed in 16 months of full-time study. For students with less than two years of relevant work experience, there is an opportunity to integrate MBA studies with work placements in a 24-month schedule of full-time study that includes work components. Previous relevant work experience (such as a co-op placement) can reduce the work requirement for this option. Space in the full-time integrated work placement option are limited by the availability of work placements. Many part-time students integrate their work commitments with their MBA studies.

Yes, it is. There must be a clarity in your mind that you want to get into media or media related jobs. Mass comm. does not mean print and electronic media alone. Plenty of government jobs ask for masters in mass comm. Public relations officers and other profiles demand this. As you have a good base of account and commerce as well, it increases your prospects to claim jobs in financial domain or banking mass communication/PR jobs. And I believe, MA in mass comm. is safer than M.Sc. or other nomenclatures of this degree.
If you have decided, then do not avoid skill development during your master degree. From where you do it matters less, how you do it is actually important.
