May 30, 2025


What is a Sump Pump?

A sump pump is a mechanical device installed in the lowest part of a basement or crawl space to remove accumulated water and prevent flooding.

Why Do Sump Pumps Matter in Real Estate?

In Canadian real estate, sump pumps are especially common in flood-prone areas or homes with high water tables.



Sump pump systems typically include:
  • A sump pit or basin where water collects
  • An electric pump that activates when water reaches a set level
  • Discharge piping that redirects water away from the foundation



A working sump pump can reduce moisture, mold growth, and structural damage. Many home insurance providers recommend or require one in at-risk properties.



Understanding sump pumps helps homeowners and buyers manage drainage risks and protect basements from water damage.

Example of a Sump Pump in Action

After a spring thaw, the sump pump in the home’s basement activates several times to divert groundwater and prevent flooding.

Key Takeaways

  • Prevents basement flooding.
  • Activates automatically in high water.
  • Essential in flood-prone areas.
  • Requires regular maintenance and backup power.
  • Can reduce insurance claims and damage.

Costly Construction, Decades Of Delays: Canada’s Project Leaders Get A New Playbook

Costly Construction, Decades Of Delays: Canada’s Project Leaders Get A New Playbook

For much of the past two decades, Canada approached major projects with a simple idea: write the contract well enough, and the project would essentially look after itself. Each risk sat with a party ready to handle it, so when something went wrong, everyone knew who to turn to.

But it hasn’t worked out that way. Canada is one of the most expensive places in the world to build, and paying top dollar still doesn’t keep projects from running late (and over budget). That’s a problem at any time, but an even bigger one today, with the transportation, water, energy, natural resource, military and information technology projects currently being planned carrying multi-billion-dollar price tags — not to mention stakes in trade, sovereignty, national unity, and climate change. For developers and city-builders, these are the projects that determine where and how growth happens.

District Energy Wants The Mechanical Room (And To Give Your Rooftop Back)

District Energy Wants The Mechanical Room (And To Give Your Rooftop Back)

Oakridge Park (via Corix)

Every residential tower gives up part of itself to equipment. From early plans, mechanical systems typically claim a room in the basement and a penthouse on the roof (the latter being prime real estate, mind you). This approach means that square footage is spoken for before the first suite is laid out.

Developers pay to build that space, but can’t sell or rent it. And today, with construction costs high and interest rate hikes back on the table, that cost is increasingly difficult to absorb.

High-rise went the other way. Just 129 new high-rise units sold in September, according to new figures from the Building Industry and Land Development Association (BILD) and Altus Group, BILD’s official source for new home market data.
