Housing here: what the census shows
The 2021 Census counted 338,503 people and 110,865 occupied homes in the City of Markham as a whole.
77% are single-detached, semi-detached or row houses, where the owner is responsible for the foundation, the drains and the sewer lateral. 16% are apartments in buildings of five or more storeys, and a further 7% are in low-rise buildings or duplexes. There, a leak commonly reaches the units below and involves the landlord or condominium corporation.
18% of households rent, which means two sets of insurance on many losses: the owner's for the building and the tenant's for belongings.

- Basement Flood CleanupA flooded basement is three problems at once: standing water, contaminated surfaces and a structure that is soaking it all up.
- Sewage Backup CleanupSewage is a health hazard, not a mess to mop.
- Burst Pipe Water DamageA split supply line can release a great deal of water before anyone notices, and it runs downhill through ceilings and walls.
- Fire Damage RestorationAfter the fire is out, the damage continues.
- Smoke and Odour RemovalSmoke travels much further than flames.
- Mold Removal and RemediationMold (or mould, as it is also spelled in Canada) is a moisture problem that shows up as a mold problem.
- Asbestos RemovalAsbestos is harmless while it is sealed inside a material and dangerous once that material is broken, cut or sanded.
- Storm Damage RestorationA storm opens the building and the rain does the rest.
- Emergency Board-Up and TarpingAn open building takes on weather and invites theft.
- Contents Cleaning and Pack-OutYour belongings are part of the loss.
