Diploma

Hi,
As you haven't mentioned your education, therefore, it will be difficult to tell whether you are eligible or not. You can check the eligibility criteria below:
Eligibility: 10+2 (any stream) or equivalent to PUC.

Hi Sabina, you can check Algonquin College, Confederation College, Fanshawe College etc. Please check the websites for specific information.

A lot of law colleges also provide Diploma in labor laws. You can check on the same and register yourself.

Hi Chetan, you cannot do a MS after Diploma. You must have a Bachelor's degree and that too with very good grades if you want to pursue your MS from Canada. Work experience is not mandatory for MS programs. It is required for MBA abroad.
