In 2017, 16.5 per cent of all CPP contributions came from Alberta workers, while just 10.6 per cent of CPP expenditures made their way back to the province. The difference between what was paid in and paid out was $2.9 billion in 2017, the most recent year for which data are available. (Alberta paid in $8.1 billion and received $5.2 billion.) Between 2008 and 2017, Albertans have contributed $27.9 billion more to CPP than retirees in the province have received back.
Were Alberta to drop out of the CPP, other provinces would have to pick up the slack by raising individual contribution rates. Were the province to withdraw, Albertans could pay as low as 5.85 per cent into an Alberta pension plan, while the rest of the country would need to up their contributions from 9.9 per cent (the 2017 contribution rate) to 10.6 per cent, the study says. The federal government already raised the contribution rate (shared equally by employers and employees) to 10.2 per cent in January, and plan to increase it to 11.9 per cent by 2023.
