Highest temperature in Toronto on December 18?

This market will resolve based on the data for the Global Land-Ocean Temperature Index for December 2025 versus the data points available for all other Decembers on record.

Note: If December 2025 is tied for first, second, or third hottest with another year, it will qualify for the bracket it ties with.

The primary resolution source for this market will be the figures found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Dec" (https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt). If NASA's "Global Temperature Index" is rendered permanently unavailable, other information from NASA may be used.
If no information for December 2025 is provided by NASA by January 31, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.

Will December 2025 be the 4th or lower hottest on record?

This is a market about the variation of consumer prices over the 12-month period ending December 2025 in Canada, before seasonal adjustment, as reported by Statistics Canada.

The resolution source for this market will be the Statistics Canada Consumer Price Index monthly report released for December 2025 (https://www.statcan.gc.ca/en/start), currently scheduled to be released on January 19, 2026. Resolution of this market will take place upon release of the aforementioned data. If no data for the specified month is released by the date the next month's data is scheduled to be released, this market will resolve based on data from the last available month.

You can find this report by clicking on the “Consumer Price Index” option under the "Key Indicators" heading on the home page of https://www.statcan.gc.ca/en/start and selecting "Table 1". The relevant figure can be found under the "% change" column for the relevant month and year compared to the same month of the previous year.

Note: the resolution source for this market will be the official monthly Statistics Canada CPI news release which reports inflation change over 12-month periods to only one decimal point (e.g. 1.9%). Thus, this is the level of precision that will be used when resolving the market. For the full release schedule, see: https://www150.statcan.gc.ca/n1/dai-quo/cal1-eng.htm?sk=3665

This market will resolve to “Yes”, if either of the following conditions are met:

1.  The C.D. Howe Institute’s Business Cycle Council publicly announces that a recession has occurred in Canada, at any point in 2025, with the announcement made by December 31, 2025, 11:59 PM ET.

2.  The seasonally adjusted annualized percent change in quarterly Canadian Real GDP (expenditure-based), chained (2017) dollars GDP from the previous quarter is less than 0.0 for two consecutive quarters between Q4 2024 and Q4 2025 (inclusive), as reported by Statistics Canada (StatCan).

Otherwise, this market will resolve to "No".

Note that any two consecutive, concurrent vintages indicating negative GDP growth will qualify, regardless of prior or later revisions. For example, if upon release, the initial estimate for Q2 2025 was negative, and Q1 2025's most recent, up-to-date estimate was also negative, this market would resolve to "Yes". If on December 31, 2025 the latest estimate for quarterly GDP in Q3 2025 was negative, this market will stay open until Statistics Canada publishes the initial estimate for Q4 2025, at which point it will resolve to "Yes" if Q4 2025 was negative or if the C.D. Howe Institute’s Business Cycle Council declares a recession by then.

The resolution source will be the official announcements from the C.D. Howe Institute’s Business Cycle Council and Statistics Canada’s estimate of seasonally adjusted annualized percent change in quarterly Canadian real GDP from previous quarters as released by Statistics Canada (e.g., as reported in the line “Gross domestic product at market prices” in Table 3 of the quarterly GDP release: https://www150.statcan.gc.ca/n1/daily-quotidien/250829/t003a-eng.htm)
