Subfloor construction front to back
It frequently changes at the point where an addition was built on.
Houses here tend to be deeper than they are wide, with rooms running front to back along a hallway. That shape matters for flooring in two ways. A long continuous run of a floating floor eventually hits the manufacturer's maximum length and needs an expansion joint, which means either a transition strip in an awkward place or switching to glue-down. And because these houses were built over a long period, the subfloor can change partway through – a rear addition frequently sits at a different height and on a different construction to the original house. Both of those get established on the visit rather than discovered when the floor is halfway down.
Long runs planned so transitions land where they are least visible.
Plywood where original panels or planks sit under the 19 mm minimum.
Where a rear addition sits at a different height to the original house.

A step of even half an inch needs a planned transition rather than a fudged one.
A long floating floor needs an expansion joint or a switch to glue-down.
Older basements here often lack an underslab vapour barrier, which the moisture reading will show.
Houses here grew over decades, and the rear addition is nearly always built to a different standard than the front. Different joist spacing, a different subfloor panel, sometimes a step of half an inch that nobody notices until a continuous floor crosses it. We take levels at the junction on the site visit rather than assuming the house is one consistent structure, because that single measurement decides whether you get a level run or a planned threshold.

Ontario Flooring replaced old carpet in our bedrooms with new flooring. They worked efficiently, helped us understand the options, and completed the installation on schedule.
The team refinished our existing hardwood floors and brought them back to life. The colour looks great, and the final finish is smooth and consistent.
It gets a planned transition, or the lower side gets built up if the difference is small enough to be worth it. What matters is deciding that before the floor is ordered, because it affects how much material and how many thresholds you need.
Every floating product publishes a maximum continuous run, and a long Toronto house can exceed it front to back. Glue-down removes the limit entirely, which is often the better answer in a deep house.
It depends on the moisture reading. Older basements in this area often have no vapour barrier under the slab, which means the reading matters more than usual. Waterproof-core vinyl plank is the safest specification when the number is borderline.
