Water Table

Understand the water table in Canadian real estate — how it affects construction, drainage, and property risk in flood-prone or rural areas.

Water Table



What is the Water Table?

The water table is the level below the surface of the ground where soil and rock are fully saturated with water.

Why the Water Table Matters in Real Estate

In Canadian real estate, a high water table can affect drainage, basement flooding risk, foundation design, and the long-term integrity of a property.


Key implications include:
  • May require sump pumps or drainage systems
  • Affects location of septic systems and wells
  • Can increase risk of water infiltration in basements


Builders and buyers should assess the local water table before constructing or purchasing homes in areas with poor drainage.


Understanding the water table is essential for site planning, flood prevention, and long-term home maintenance.

Example of the Water Table in Action

A buyer building a rural home orders a geotechnical report to confirm the water table is low enough for a standard basement and septic system.

Key Takeaways

  • Subsurface level where ground is saturated.

The Burnaby Lake Village master-planned project has officially exited creditor protection, according to filings in the Supreme Court of British Columbia, resolving a conflict between the two local developers that partnered on the project.

Burnaby Lake Village is set for the 19-acre property at 6800 Lougheed Highway in Burnaby, directly adjacent to the Millennium Line SkyTrain's Sperling-Burnaby Lake Station, where Peterson and Create Properties were planning nearly 6,000 new homes across 14 mixed-use buildings between the heights of 12 and 25 storeys.

Low Immigration, High Supply Pull Rents Down For Ninth Straight Month

Canadian rents continued to slide in June, with the most pronounced declines reported in BC and Alberta and in Canada's largest cities. Driving the decline is a combination of low immigration and over supply leading to higher vacancy rates and longer vacancy terms, under which landlords are beginning to cave.

“Rent decreases at the national level have been mild so far, with the biggest declines mainly seen in the largest and most expensive cities," said Shaun Hildebrand, President of Urbanation. "However, it appears that the softening in rents has begun to spread throughout most parts of the country.”

Northern BC Project Could Be Blueprint For Canada’s $25B Modular Push

NorthStar Development's 40-unit Estrella rental project in Prince Rupert, BC.

Developer Gordon Wylie has worked on office buildings, all types of residential, real estate investment, and major shopping mall redevelopments, including project lead on the early iteration of Oakridge Mall during his tenure as Vice President, Development, for Ivanhoe Cambridge.

He was also key in the company’s purchase of Metrotown Centre, an expansion that helped transform Burnaby. Wylie says he’s always up for a challenge, and so it fits that he’s now one of the rare developers who’s embraced modular construction to bring desperately needed rental housing to BC’s northern city of Prince Rupert. The five-storey, 40-unit Estrella rental project is a test case for his company, NorthStar Development Corp., which handled the financing, development, and construction management of the new rental building. NorthStar builds office, retail, industrial, mixed use, and rental and condo housing, and partners with non-profits to deliver below-market housing.

Hullmark Acquires Interest In Jane Finch Mall, Will Manage Redevelopment

A fixture of Toronto's Jane and Finch neighbourhood for upwards of 50 years, Jane Finch Mall has seen its fair share of change, from updated stores and restaurants to the addition of new grocery offerings to meet the evolving needs of the community. And it’s in for its biggest transformation yet. In the coming decades, the property at 1911 Finch Avenue West will be redeveloped into seven mixed-use blocks with a dozen new mid- to high-rise buildings and over 4,600 new residential units.

The proposed redevelopment, which comes from an affiliate of Southdown Builders Brad-Jay Investments Ltd., got the City's go-ahead in August 2024, around eight months after the company filed plans for Phase 1 of the master plan. Most recently, Brad-Jay has announced that they have brought on prominent investment and development company Hullmark to see the transformation through. The project will join similarly ambitious development endeavours in the company’s portfolio, including Beltline Yards, a master-plan community in the works from Hullmark and BGO.
