Changing institute in Canada is not an issue also transferring credits is a very normal process here.
Below is the scenarios explained in CIC (link --> http://www.cic.gc.ca/english/resources/tools/temp/students/post-grad.asp?s=1 )
In cases where a student has transferred between designated learning institutions, the combined length of study must be at least eight months.
In cases where a student graduated from an eligible institution, after having transferred from an ineligible institution, only time spent in the eligible institution will be counted. Once again, time spent in the eligible institution must be at least eight months.
Example 1: A student attends a foreign post-secondary institution and transfers to an accredited provincial or territorial post-secondary institution in Canada in order to complete their studies. Under this scenario, if the qualifying educational credential is issued at an institution outside of Canada, they would not qualify for a post-graduation Work Permit. However, if they did receive their educational credential from a recognized Canadian educational/training institution, they may be eligible for a post-graduation work permit only for the length of time they studied in Canada.
Example 2: A student attends their first year at a private post-secondary educational institution in Canada not recognized under this program but then transfers to a recognized post-secondary institution. Under this scenario they may be eligible for a post-graduation work permit but only for the length of time they studied at the designated post-secondary institution.
Example 3: A student completes a program of study at a designated learning institution and transfers these credits to another designated learning institution. Under this scenario, they must submit a letter of acceptance from the second institution indicating that the credits are accepted to complete the program at the second institution.
