Granovsky v Canada (Minister of Employment) 2000 SCC 28  1 SCR 703
Headnote from the case:
"The appellant claimed to have suffered an intermittent and degenerative back injury following a work-related accident in 1980. He was assessed to be temporarily totally disabled at that time. Prior to his accident, he had made Canada Pension Plan (CPP) contributions in six of the ten previous years. The appellant was profitably employed from time to time following his accident but maintained that his back condition continued to deteriorate and that the disability became permanent in 1993, at which time he applied for a CPP disability pension. His application was refused by the Minister of Employment and Immigration and refused again by a review tribunal in part because he had only made a CPP contribution in one year of the relevant CPP 10-year contribution period prior to the date of application and thus had what was considered to be an insufficiently recent connection to the work force. He could not bring himself within the “drop-out” provision (made available to applicants who suffered from severe and permanent disabilities) under which periods of disability are not counted in the recency of contribution calculation. Among the issues raised by the appellant was whether the CPP infringed s. 15(1) of the Canadian Charter of Rights and Freedoms because the contributions requirement fails to take into account the fact that persons with temporary disabilities may not be able to make contributions for the minimum qualifying period in s. 44(1) because they are physically unable to work. The appellant was unsuccessful both before the Pension Appeals Board and before the Federal Court of Appeal."
