1- what proof of finance i should show at the POE? i already showed send it to the embassy to get the visa ? This depends on the immigration officer. All you need is to make sure that you've money on you at least for your first month and arrangement has been made to pay for your fees and others. Just relax, you'll be found since the visa officer has already assessed your appilcation and deemed that you've the means to study in Canada. At the POE, it's rare to request for bank statements.
2-Please help me on this, i applied on 2013 to a 4 years program now i want to get a 1 year of study, i'm afraid if i present an acceptance with 1 year only i might be denied of entry so i renewed the 4 years study acceptance letter to 2014 should i show it on border to be good to enter? Here, I hope you've already notified the visa office which issued your study permit. If there is anything contrary to the rule, they'll let you know. If no such message, it means everything is fine. Just show the CBSA your new acceptance letter. Leave the others to them.
and what this new regulation means
Current regulations
Applicants must show that they intend to pursue studies in Canada when applying for a study permit. You don't really have a problem here: you've an acceptance letter.
New regulations, as of June 1, 2014
Applicants must enrol in and continue to pursue studies in Canada. Failure to do so could lead to removal from Canada. The statement is self explanatory. If you fail to enrol or terminate your program, then you've to leave Canada. If you finish your 1 year program, you may apply for another program while you're in your final semester and continue your studies in Canada should you wish. You may also apply for PGWP after your 1 year program to work in Canada for 1 year. Some universities organize seminars on immigration matters to foreign students during orientation. Make sure you attend one if there is such an opportunity in your university.
