Hello, for me the open heart surgery( twice ) took place 11 years ago. Currently my application is submitted for work permit and it in progress. I am on warfarin which needs to be taken daily. Is this history causes any delays in approval and subsequent issues for PR as well? And also not sure, if this forum is right to ask this question.. B'caz, I have seen on web that warfarin is slowly getting stopped in Canada and other alternative blood thinners are available. So what would be the average cost of blood thinners in Canada annually? What is the procedure to get the prescribed medicine if change in blood thinner is needed and time frame in getting those tests done?
