How to keep my Student visa status valid?

[ashish.gurthula]

I am an International student enrolled in Post graduate studies for winter intake 2018. I have completed the winter semester but due to my medical condition i had to drop the summer semester. When i came back to resume my studies, college authorities said that my program semester is not available in fall so i have to drop fall semester and apply for winter semester 2019. When I called the Immigration Canada people, they told me to enroll into a course in Fall semester to keep my student status or change my status to visitor visa. Now i want to keep my student status by no college is giving me 1 semester programs for Fall. The colleges with 1 semester programs are already full. So, Can you please help me on this issue?
