Wrong information. It clearly states that your visa will be issued based upon when you "applied" not when the visa was issued. Refer to cic.gc.ca it clearly states that applicant applying prior to June1st will be given visas on old conditions.
Note: Under the new rules, your study permit will become invalid 90 days after you have completed your study program. If you switch to a shorter-term program or finish your studies early, your study permit will expire 90 days after your study program has been completed. Your program is considered complete when you receive written notification of program completion (for example, a transcript or an official letter) from your institution or once you obtain your degree, diploma or certificate. This does not apply to you if your study permit application was received before June 1, 2014, or if you were issued a study permit before June 1, 2014.
Also new rules will only be for students who's file was received on or after June 1st.
