On 17 December 2019 the Canadian Institute for Health Information published statistics on drug spending, finding that in 2018 approximately 40% of drug spending was spent on 2% of beneficiaries. Of this 2%, three out of five individuals used a drug therapy that cost C$10,000 or more per year (eg, antivirals or biologics for rheumatoid arthritis or Crohn's disease). Over the past five years, the top increases in drug spending were for drug classes with average annual costs of C$10,000 or more.
