Read the unit before reading the trend
Statistics Canada's January 2026 aircraft-movements release defines a movement to include a take-off, landing or simulated approach. Its figures describe the stated historical period, not today's traffic. This is a useful warning against treating “movements” as synonymous with passenger journeys. When reading another release, verify its own definitions and coverage rather than carrying a remembered headline number into a different month or airport comparison.
Separate local activity from itinerant activity
The same release distinguishes local and itinerant movements. Repeated activity around an airport can therefore contribute to its total without representing the same pattern as flights arriving from other cities. Do not use a total alone to rank airports by passenger importance. Start by checking whether your question concerns training activity, overall operations, airline services or people travelling. Those questions need different measures, even when the charts all have airport names on their horizontal axis.
Use the reporting fields to understand the dataset
The Statistics Canada reporting instrument shows fields used to describe movements, including time, aircraft information and local or itinerant classification. It is a reference to the data structure, not a live airport dashboard. Record which table and version you actually use for an analysis. If the dataset contains separate categories, retain them through your calculation instead of combining them and later interpreting the result as though only one category had been counted.
A map snapshot has a different denominator
A public tracker displays the observations available at a chosen time and view. It does not count every airport movement in a reporting month. Even NAV CANADA's surveillance overview describes a different system from a public website's feed. You cannot validate an airport's monthly movement total by counting PocketWorld markers in a screenshot. A marker can persist across several observations, while an airport event and a unique aircraft are different counting units.
Build a fair airport comparison
Choose the same reporting period, table, category and airport coverage for both places. Keep the raw count beside any percentage change, and note missing or revised data. Use similar seasonal periods when your question concerns a longer-term trend. Do not replace unavailable values with zero or label an airport inactive because it is absent from a selected table. PocketWorld can help you locate airports and explore available aircraft reports; official statistical products answer the historical counting question. This guide supplies no new airport ranking and no claim about current national traffic volume.
