How high is the lot, and which way does the ground fall?
Natural Resources Canada's medium-resolution elevation model gives the height of the ground every 30 m across Canada. The check reads the height at the address and how the ground rises or falls within 100 m of it.
Report check: Height and slope of the land. Entry reviewed 20 Oct 2026; each source below shows its own data date.
How a report shows itsample, made-up home
The lot sits at 92 m above sea level. Ground falls about 3 m toward the creek within 100 m.

What the record is
The model is built from satellite and airborne measurements and records the ground surface, not buildings. At 30 m resolution it shows the shape of a neighbourhood (a hill, a valley, a creek bank) rather than the grading of one lot.
The report line gives the height above sea level and the direction and amount of fall within 100 m. It sits with the water checks because low ground near a creek is where flood plains and regulated areas tend to be.
Where it runs
This check runs at every Ontario address, from provincial and federal records:
