In most Canadian universities and colleges, the academic year is divided into two semesters, the fall semester (Sept-Dec), and the winter semester (Jan-May), with a short vacation at Christmas. Many colleges also offer a summer semester beginning in May.
University deadlines for the September session vary from institution to institution, though are generally from mid December to the end of March.
Colleges may have a rolling admission policy and will accept applications while processing time still permits.

In Canada the school year for elementary and high school consists of 178 to 200 days, depending on jurisdiction, but several days may be deducted from this total for professional development and administrative duties, resulting in approximately 187 teaching days per year for most jurisdictions. Elementary students receive approximately 950 hours of instruction and secondary students receive approximately 1000 hours per year.
Generally in English Canada, high schools run on a two-semester arrangement, also known as fall and spring semester, the first semester starting from the day after Labour Day in September to mid-January and the second running from early February until the Thursday before the last Friday in June. The semesters are often divided into two terms each. Some schools in Canada run on a trimester system, the first running from September to January, the second from January to March or April, and the third from March or April until June. The trimester is more common in elementary and middle schools (Kindergarten - Grade 8) than in high schools (Grade 9 - Grade 12). Most universities and colleges usually run from early September until the end of April or early May. Often, this winter session is split into two terms running September to December and January to April. Various forms of summer studies may be offered May to August. Some, such as Simon Fraser University, run a full tri-semester system, providing full courses during summer. There are a few school boards in Canada experimenting with year-round schooling
