The single most useful timing signal in construction sales is not when a permit gets approved. It is how long the approval takes. In Vancouver, a new-building permit takes a median of 159 days to move from application to issuance. In Thunder Bay, the median permit clears in 11 days. If you sell to contractors or owners, that 148-day gap changes when you should be reaching out, what stage the project is in, and how long your window stays open.
We pulled these building permit timelines from our own dataset of more than 3 million permits across 31 Canadian cities, current as of July 2026. Below are the real numbers, by city and by work type, drawn from the trailing 24-month window, so you can plan outreach around how a market actually moves instead of guessing.
How Long Permits Take, By City
Application-to-issuance time is the number of days between when a permit is filed and when it is issued. Only six Canadian cities publish elapsed processing days in their open data, and we only counted cities with at least 50 valid records. The spread is wide enough that a strategy that works in one city is wrong in another.
| City | Average days | Median days | Permits (24 mo) |
|---|---|---|---|
| Thunder Bay | 29.9 | 11 | 1,843 |
| Kelowna | 38.2 | 12 | 2,967 |
| Montreal | 50.8 | 17 | 40,780 |
| St. Catharines | 61.0 | 31 | 1,985 |
| Toronto | 82.1 | 32 | 41,436 |
| Vancouver | 112.5 | 69 | 9,652 |

Two things stand out. First, the median is almost always far below the average, which means a minority of slow, complex permits drag the average up while most permits clear faster. Watch the median for the typical case and the average for how bad the tail gets. Second, Vancouver stands out clearly: a 69-day median against 11 days in Thunder Bay and 12 in Kelowna. Toronto and St. Catharines are similar to each other at around 31 to 32 days at the median, though Toronto’s average is higher because of complex large-project outliers.
Why the Timeline Is Your Outreach Window
A permit’s processing time is the period during which the project owner is committed enough to file but has not yet broken ground. That is the window to introduce your services, line up subcontractors, or get a quote in front of a decision-maker before the job is locked.
In a fast market like Thunder Bay, with an 11-day median, that window is days, so speed matters more than polish. In Vancouver, with a 69-day median, you have weeks to build a relationship before the project moves. Knowing the local timeline tells you whether to fire off a same-day message or run a multi-touch sequence.
Work Type Changes Everything
City-level numbers hide a second signal: the type of work. Within Vancouver alone, timelines range from under a month to most of a year depending on what is being built.
| Vancouver work type | Average days | Median days | Permits (24 mo) |
|---|---|---|---|
| Temporary Building / Structure | 21.9 | 12 | 81 |
| Salvage and Abatement | 60.7 | 28 | 927 |
| Addition / Alteration | 71.6 | 41 | 4,953 |
| Demolition / Deconstruction | 154.9 | 120 | 1,422 |
| New Building | 198.8 | 159 | 2,301 |

A new building in Vancouver takes a 159-day median to get issued, nearly four times the 41-day median for an addition or alteration. If you supply trades that come in early, like demolition or abatement, a new-building permit filed today is a job you can plan for months out. If you do quick renovation work, the addition/alteration timeline is your realistic pipeline.
How to Use These Building Permit Timelines
Three concrete moves from the data above:
- Match your follow-up cadence to the local median. An 11-day-median city needs immediate outreach; a 69-day-median city rewards patience and relationship-building.
- Segment by work type, not just city. A demolition contractor and a renovation contractor reading the same Vancouver permit feed should act on completely different timelines.
- Use the average-versus-median gap as a complexity flag. When the average is far above the median, expect a slow, complex subset where early positioning pays off most.
One caveat worth stating plainly: this data does not include a permit status or outcome field, so it cannot tell you which applications were approved versus denied. It measures how long issuance takes, not the odds of approval. Treat it as a timing signal, not a prediction of whether a specific project will go ahead.
Conclusion
Building permit timelines are the most concrete construction sales signal available, and they vary enormously: an 11-day median in Thunder Bay, a 159-day median for new builds in Vancouver. Knowing your market’s real numbers tells you when to reach out, how hard to push, and how long your window stays open.
