Hey, maybe this can help:
A Message from Citizenship and Immigration Canada (CIC)
On January 31, 2005, CIC introduced a new policy for international students in post-secondary studies in Canada. These students can now transfer between programs of study and institutions (for example, university to college) without applying for a change to the conditions of their Study Permit. They can also transfer between public and private institutions.
Previously, most international students could transfer between the same type of educational institution (for example, university to university, or college to college), but could not transfer between different types of educational institutions (for example, university to college).
This policy applies to students who have a valid Study Permit for training or studying at the post-secondary level, such as:
•University
•Community College, CEGEP, Institute
•Private university, career college, academy, school or training institution
•ESL/FSL and other language training
It does not apply to students in Kindergarten to Grade 12 programming.
All post-secondary students currently studying in Canada with a valid Study Permit are covered by this policy. You do not need to submit an IMM1249 (Application to Change Conditions, Extend my Stay or Remain in Canada) to transfer between institutions. For any other changes to your Study Permit, consult Information for Foreign Students or speak to your International Student Advisor.
If you are unsure as to whether or not you need a new Study Permit, contact SDC's International and Exchange Student Centre by e-mail at iesc @ uwo.ca, by telephone at 519-661-2111 ext. 85908, or in person (you can drop by SDC's International and Exchange Student Centre, WSS 2120, OR book an appointment to meet with an International and Exchange Student Centre's staff member by calling 519-661-3031 or visiting SDC's Reception in WSS, 4100).
