A sporting event's economic impact is an estimate of the activity linked to the event across a local or regional economy. It is not the same as the organizer's profit, the value of all tickets sold, or money permanently added to government budgets. Proper studies distinguish visitor spending from subsequent effects on businesses and jobs.
The measures are not interchangeable
| Measure | What it describes |
|---|---|
| Visitor spending | What qualifying spectators and participants spend on travel, lodging, food and other purchases |
| Economic output / activity | Total business activity associated with spending and economic linkages |
| GDP contribution | Value added to production, not the full value of every transaction |
| Employment impact | Estimated jobs or full-time equivalents supported during the model period |
| Organizer profit | Revenue minus the organizer's costs, from financial accounts rather than an impact model |
A published Canadian event example
Sport Tourism Canada's published results reported that the 2025 Special Olympics Ontario Summer Games generated approximately C$3.0 million of total economic activity in Ontario, including C$2.48 million in Brantford. Those figures measure modelled economic activity, not a claim that the organizing committee earned C$3 million in cash profit. They also illustrate why readers must specify the geographic boundary: Brantford's impact is a subset of the wider Ontario estimate.
How do economists build an estimate?
Sport Tourism Canada's STEAM model combines visitor-expenditure profiles with event operations and relevant capital costs, then applies economic modelling. Canadian Heritage's CAHSEIM framework similarly distinguishes direct, indirect and induced effects. Direct effects include spending immediately attributable to the event; indirect effects arise through suppliers; induced effects include additional household spending associated with supported incomes.
What might the headline leave out?
A study's assumptions, what counts as genuinely new visitor spending, displacement of other visitors and how jobs are measured can change the interpretation. Even a reliable positive economic-activity estimate does not automatically prove that taxpayer subsidies were worthwhile. Compare the study's geography, methods, baseline and public costs before accepting the headline as a complete return-on-investment assessment.
