Why does rep by pop not apply to PEI?

Rep by pop, or representation by population, does not apply to Prince Edward Island (PEI) due to its unique political and historical context. PEI has a small population, and its political structure is influenced by the need to ensure that smaller provinces have equitable representation in the federal government. As a result, the province maintains a minimum number of representatives in Parliament to ensure that its voice is not overshadowed by larger provinces, balancing population-based representation with regional interests.
