Hi,
The comparison can be made between similar things. Dental hygiene and computer engineering, they have absolutely no relation to each other and they are completely different sectors, both are in demand in their respective fields.

If you like mathematics then you should opt for accounts or finance courses, they are the top sectors in Canada and they to have globally relevance. Rest will depend on your interests and aptitude.

Hi Aman,
To apply for Ph.D. programs you must write to the universities, the department supervisors precisely. You must share your research ideas or proposal, they will accept you only if they find your research thoughts interesting. Research on the universities, check what all universities actually have to research about. Scholarships and funding is something you have to discuss with the supervisor. In US full funding is available, however, countries like UK do not guarantee or offer any funding.

You need to prepare for GMAT exam.

The degrees and certificates issued by Indian universities / institutes are not valid for applying for jobs abroad. You need to pursue a relevant course in cosmetology to get a job in Canada. The courses available in Canada are for 6 months, 9 months and for 12 months till 2 years.
These are the short term courses / Diploma / certificate courses.

Hi Maninder,
You are eligible but you have to be extra careful with the university application. Work on your SOP and LORs. Also you can apply for SPP colleges only since universities require more than 70 to 75%.

Hi Dinesh,
If you want to pursue a 2-year course, you can apply for an advanced Diploma or post secondary Diploma. You must ideally look for Bachelor's degree programmes with the good academic grades you have. Check for admission requirements on college websites, enquire about co-op options, career assistance they provide and then apply.

Hi Emran,
