To answer this controversial debate question, “should medically necessary physician and hospital care be a right or a privilege?” we should identify the differences between a right and a privilege. In Oxford English Dictionary Tenth Edition, a right is defined as the authority to perform, publish, or film a particular work or event. Therefore, the right to health care can be considered the right to have health care and the means to take action in one's own health care, regardless of class. A privilege is defined as a special right or advantage for a particular person or group. The Canadian Health Act does not explicitly indicate whether we have the right to access medically necessary physician and hospital care or not. We have health care as a privilege rather than a right because those who are paying taxes in Canada have the luxury to live with better health system. Also Based on the definitions of the two words, I would say that having a health body should be a right; however, medically necessary physician and hospital care should be a privilege. With an increasing amount of taxes given to the Canadian residents, we deserve to have more privilege to medical services. We can increase our privileges by effectively allocate our resources, stricken pharmaceutical system, and educate others how we all contribute to the health system.
Every person has a right to live healthy life. Health care as a right means that people who have previously been unable to afford healthcare need no longer live in fear of ill-health. This benefits everyone. No-one should live in fear, and no-one should wish others less fortunate to do so. In other words,rights to a health care system should be the fundamental of all health care systems. However in reality, not everyone have access to the services. Many people believe health care is a right of each and every human being. If all individuals are equal, should they all have the equal right to health care? At this time, anyone with a care card has the privilege to be hospitalized at no cost and certain amounts of medical expenses are subsidized. Nevertheless, health care is a limited and expensive resource. Its expenses are well known, and the implementation of a health care right might not guarantee there will be health care to distribute. In other word, If we agree that health care is a right, there would not be enough resources to allocate to the individuals
For instance, if one with serious disease requires one physician, we would need a lot more physicians to care for the rest of people with serious illness in the rehabilitation centers except, finding the right physicians are difficult and expensive.
In Canada, the publicly funded health insurance company, Medicare, provides coverage to all Canadian residents. The fees paid by Canadians for medically necessary services are those included in taxes. However the arguments against universal health care in America are substantial. It is generally believed that in a free market society, when the government involves itself in organizations competing for consumers, costs increase due to regulations or standards. Currently there are a number of insurance companies competing for the business of American consumers, creating a need to provide the best service for the lowest price.
Another argument to be considered is whether a universal health care system could create a cap on the salaries of health care workers in America. This cap could discourage skilled individuals from choosing to work in the United States if it is possible for them to obtain a higher wage elsewhere.

Your grammar is mostly OK.
Toward the end of the first paragraph, you should change these sentences: suggestions [in brackets]
We have health care as a privilege rather than a right because those who are paying taxes in Canada have the luxury [of living] with [a] better health system. Also[,] [b]ased on the definitions of the two words, I would say that having a health body should be a right; however, medically necessary physician and hospital care should be a privilege. With [the] increasing amount of taxes [imposed on] Canadian residents, we deserve to have more [access] to medical services. We can increase our [access] by effectively [allocating] our resources, [relieving the over-burdened] pharmaceutical system, and educate others [about] how we all contribute to the health system.
In the 2nd paragraph:
In other words,[ ]rights to a health care system should be the [basis] of all health care systems. [in reality,however,] not everyone [has] access to the services. Many people believe health care is a right of each and every human being. If all individuals are equal, should they [not] all have the equal right to health care?
In other word[s], [i[f we agree that health care is a right, there [might] not be enough resources to allocate to [all] individuals[.]
3rd paragraph:
For instance, if [an individual] with [a] serious disease requires one physician, we would need [many] more physicians to care for the rest of [the] people with serious illness[es] in the rehabilitation centers, [but] finding the right physicians [could be] difficult and expensive.

That concluded my suggestions for grammatical and vocabulary corrections.
i believe there are some issues with the logical development of your case, and you should summarize your arguments in a final paragraph. (Don't just drop off with examples, finish by listing main points and restating your thesis in the conclusion.)
