The Tourism Regional Economic Impact Model (TREIM) is a data analysis simulation tool.

It helps organizations and people who are interested in tourism to learn more about the economic impact of tourism in Ontario.

The model is capable of simulating tourism-related economic impacts from 2010 to 2025, such as:

  • economic impact of specific tourism events
  • impacts on the supply side by tourism industry sector
  • impacts by type of capital project for the chosen region

Future versions of the model will incorporate more recent data as it becomes available.

What you can learn

TREIM includes modules on:

  • visitor spending — estimates the economic impact of tourism spending in a specific region and/or for a specific event. There are 17 built-in activity options, including festivals, golfing, casinos
  • operational expenses — estimates the economic impact of operating an ongoing business, such as an attraction, retail business, hotel or restaurant
  • investment expenditures — estimates the economic impact of investing in or building a tourism facility such as an attraction, retail business, hotel or restaurant
  • convention centre activity — estimates the economic impact of a convention, including the spending of delegates and exhibitors as well as production costs


Features that you can use to get tourism economic data include:

  • timeframe for analysis — 16-year range including past, present and future
  • geography — Ontario, 16 travel regions, 49 counties, districts and regional municipalities, 43 census metropolitan areas and census agglomerations
  • users are guided through a series of steps to enter their inputs
  • an output report can be printed or saved
  • once the report is run all inputs are deleted
  • no user fees
  • updated annually

Using the tool effectively

You are required to provide information on the type of tourism activity you wish to simulate.

To get the best results, make sure your inputs are accurate.

Setting up a query

You should include the following information when setting up a query:

  • general
    • report title
    • the geographic area where the impact takes place
    • the impact year
    • “Yes/No” choice for induced impacts (household spending and business investment)
    • “Yes/No” choice for the inclusion of property taxes
  • project-specific
    • visitor spending/number of visitors
    • operational expenses
    • investment expenditures
    • convention spending (delegates/exhibitors/production costs)

Visitor definition

For the purpose of this tool, a visitor is someone who takes:

  • an overnight out-of-town trip
  • an out-of-town same-day trip of 40 kilometres or more away from their home

The trips do not include commuting to work or school, being on a diplomatic mission, going shopping as part of a regular activity, or going to regular appointments for doctors or religious ceremonies.

For international visitors, it excludes students who stay in Canada for 75 or more nights.
