"Learning Disability: One of a number of neurodevelopmental disorders that persistently and significantly has an impact on the ability to learn and use academic and other skills and that:
affects the ability to perceive or process verbal or non-verbal information in an effective and accurate manner in students who have assessed intellectual abilities that are at least in the average range;
results in (a) academic underachievement that is inconsistent with the intellectual abilities of the student (which are at least in the average range), and/or (b) academic achievement that can be maintained by the student only with extremely high levels of effort and/or with additional support;
results in difficulties in the development and use of skills in one or more of the following areas: reading, writing, mathematics, and work habits and learning skills;

may be associated with difficulties in social interaction (e.g., difficulty in understanding social norms or the point of view of others); with various other conditions or disorders, diagnosed or undiagnosed; or with other exceptionalities;
is not the result of a lack of acuity in hearing and/or vision that has not been corrected; intellectual disabilities; socio-economic factors; cultural differences; lack of proficiency in the language of instruction; lack of motivation or effort; gaps in school attendance or inadequate opportunity to benefit from instruction."

Supposedly, all of the provinces have some form of sped regs, with varying degrees of support.
