How low it gets here
Of the 1,471 restrictions in Ontario, 236 are under 2.5 m, 43 sit between 2.5 and 3.2 m — the band where a typical motorhome has to stop — 101 between 3.2 and 4.0 m, and 466 above 4.0 m. The median signed clearance is 4.00 m.
What the numbers leave out
625 of them state no height at all. That is not a clear road: somebody recorded a limit without a number. Treat those as obstacles of unknown height. Where nothing is signed, the general limit in Canada applies — 4.15 m.
Questions
How many low bridges are there in Ontario?
1,471 height restrictions of every kind are recorded in Ontario: 236 under 2.5 m and 43 between 2.5 and 3.2 m, the range that stops an ordinary motorhome.
What is the lowest bridge in Ontario?
The lowest clearance a road vehicle can still pass is 2.00 m, and the table above starts with it. Anything signed lower is a gate or a barrier rather than a road.
How current is this data?
It is rebuilt every week from OpenStreetMap; these figures were measured on September 18, 2026. A restriction nobody has mapped is not here, so above 3 m plan the route before you set off.
