Obtain official documentation from an appropriate professional with a clear explanation of how the circumstances directly affected your academic grades. Your doctor, social worker or teacher familiar with the situation may be the person to go to for this. Official documentation should state the dates at which the circumstances began, how long they continued and whether or not the situation has improved or is being managed.
Look at the admissions materials from the school you are applying to. Underneath the section outlining "Admissions Requirements," there may be a clause specifically mentioning "Extenuating Circumstances." This section should tell you where to get any required forms and whom to send them to. You may be directed to the admissions office, registrar or graduate school.
Look for sections that might apply specifically to your situation. Many universities in Canada have special programs and criteria for homeschooled students, students with special needs, aboriginal students, mature students, students with documented disabilities and those who need enriched support. Carleton University, University Canada West and The University of Toronto at Scarborough all offer such programs.
Contact the Admissions Office, Registrar or Graduate School for instructions if there is no mention of extenuating circumstances in the admissions materials from the school.
Prepare an essay or letter if required. Be sure to follow the instructions given by the school including word length, types of circumstances permitted and documentation. Show a draft to someone and either write out neatly or type on plain white paper with blank ink.
