The Municipal Sustainability Initiative (MSI) was Alberta's major provincial grant program providing municipalities with funding for infrastructure and operating needs. Launched in 2007, MSI delivered billions of dollars to Alberta municipalities based on population and other factors. Municipalities valued MSI's flexibility, allowing local decisions about project priorities, and its predictability for long-term planning. MSI has been transitioning to the Local Government Fiscal Framework (LGFF), restructuring provincial-municipal funding relationships. The program demonstrated provincial commitment to municipal infrastructure while giving communities flexibility to address local priorities. MSI's evolution reflects ongoing discussions about sustainable municipal funding.
