Water damage in Markham: what is different here
West Thornhill was hit hard by the storm of 19 August 2005, which led the City to start a long-term flood control program for the area.
The Rouge River and its tributaries run through Unionville and Markham Village, and the Don through Thornhill.
Older neighbourhoods built before modern stormwater ponds are more exposed to sewer surcharge during intense rain.
Floodplains and who regulates them
Toronto and Region Conservation Authority regulates the Rouge and Don floodplains in Markham. Conservation authorities publish floodplain mapping and issue flood watches and warnings, which are worth following during spring melt and summer storms. Ontario is merging its 36 conservation authorities into nine regional bodies, expected to take effect on 1 February 2027, so the name of the body responsible will change.

Housing here: what the census shows
The 2021 Census counted 338,503 people and 110,865 occupied homes in Markham.
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.

What we handle locally
- Water Damage RestorationWater keeps moving after the leak stops.
- 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.
- Reconstruction and RebuildThe emergency work removes what was ruined.
