Canada can afford to eliminate poverty, support the middle class and dramatically shrink the gap between the rich and poor by introducing an annual basic income of $22,000, according to a new report.

The unconditional stipend for adults over 18 would come with an annual price tag of between $134 billion and $637 billion, depending on three options explored by the Basic Income Canada Network in a report being released Thursday.

“Basic income in Canada is not a question of possibilities, but of priorities,” said the report’s co-author Sheila Regehr, chair of the network.
