When Apple products are labeled as obsolete, these products lose official Apple repair support. Products are usually rendered obsolete five to seven years after manufacturing has been discontinued, making the parts no longer available to repair staff. The products that have been rendered obsolete for Canada starting December 31, 2016 include the MackBook Pro 15-inch (early 2011), MacBook Pro 17-inch (early 2011), Mac mini (early 2009), and MacBook 13-inch (mid 2009).
