If the company you are working for in India qualifies as a "Canadian Business" as described below then you have nothing to worry about as you have maintained your permanent resident status of Canada.
The time spent working for a Canadian company in india will NOT count towards your application for Citizenship. You must live in Canada for 3 years before you can apply for Canadian citizenship.
What is a Canadian Business?
Canadian Business
Only some businesses qualify as a Canadian business for the purpose of satisfying your residency obligations. To qualify as a Canadian business, the business must fulfil one of these three definitions:
The business is incorporated under Canadian or provincial laws and has an ongoing operation in Canada.
The business is an enterprise, other than a corporation described above, that has an ongoing operation in Canada and satisfies the following conditions:
It is capable of generating revenue and is carried on in anticipation of profit; and
Canadian citizens, permanent residents or Canadian businesses as defined above hold a majority of voting or ownership interests.
The business is an organization or enterprise created by the laws of Canada or by the laws of a province of Canada.
Excluded businesses:
An enterprise, corporation or organization is not a Canadian business if it exists primarily to allow permanent residents to comply with their residency obligations during a stay outside Canada.
Qualifying Employment outside Canada
The term “employed on a full-time basis by a Canadian business or in the public service of Canada” means:
you are an employee of, or under contract to provide services to, either a Canadian business, the public service of Canada or the public service of a Canadian province; and
you are assigned as a term of your employment or contract on a full-time basis to either:
a position outside Canada;
an affiliated enterprise outside Canada; or
a client of the Canadian business or the public service outside Canada.
