Invitation letters

The Government of Canada has recently instituted new regulations for visitors coming to Canada. If you do not have Canadian citizenship or landed immigrant status and plan to give a talk at the conference, we will issue you a letter of invitation that you may present to the Canadian customs officials at the border crossing. Please contact Lis D’Alessio at as soon as possible for assistance.
