How long can I become a Canadian citizen after getting a maple leaf card?

According to the Canadian Citizenship Law, permanent residents must live in Canada for three of the four years and meet other conditions, such as English proficiency, before they can be naturalized. However, there is no clear definition of the word "domicile" in the law. In the federal court of Canada, there are two different schools of judges who have made different interpretations of the word "domicile". Some federal court judges ruled that as long as it can be proved that this person's life center is in Canada, this person's residence is in Canada, regardless of whether he/she actually lives in Canada. These judges believe that as long as his/her home is in Canada and his/her departure is only temporary, once these temporary factors disappear, he/she will return to his/her home in Canada, then the person's residence should still be regarded as in Canada. However, a federal court judge ruled that the law requires you to live for three out of four years, that is, you have actually lived for three years, not a day less. This is the opinion of two different judges in the federal court. A federal court case is 1978. The applicant has been studying in the United States for a long time and has not lived in Canada for three years. The applicant's parents are not in Canada, he is unmarried and only some friends are in Canada. During the winter and summer vacations, the applicant returned to Canada to live for a period of time and visit friends. The judge finally concluded that when the applicant left Canada, he had settled in Canada. He is only a foreign student in America, so this is temporary. His address is actually in Canada, so the focus of his life is still in Canada. Therefore, he met the requirement of living for three years. Although he often left the country for the United States during these three years, his application for naturalization was approved. There is also a federal court case of 1995. The litigant comes from Taiwan Province Province and owns real estate and company property in Canada. His house is worth 2 million Canadian dollars. He and his spouse invested100000 Canadian dollars in a golf course and 750000 Canadian dollars in another company. In the third year after emigration, he was employed by a sporting goods company, and the company sent him back to Taiwan Province Province to be the manager of purchasing department and the head of production department. He accepted the job because his father in his forties needed his care in Taiwan Province Province. He only lived in Canada for 25 1 day for four years. Although the income in Canada is declared, the annual income is less than 18000 USD. The judge finally decided that the focus of this person's life was not in Canada, so he could not be considered to have lived in Canada. His application for naturalization was eventually rejected. There is also a federal court case of 1997. The applicant has been in Asia for a long time because of the need to export Canadian products. His spouse and children both live in Canada and have become citizens. He himself is an "astronaut" who travels between Canada and Asia. His annual exports amount to more than10 million dollars. He owns a house, a car and a bank account in Canada. The judge's final conclusion is that the focus of his life is still in Canada, so although he has not actually lived in Canada for a long time (physically speaking), he still meets the requirements of three years' residence and entry conditions. So his application was approved.
