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.

After much anticipation, the City of Vancouver has finally unveiled the new Granville Street Plan that will guide the future of the critical business, employment, and entertainment hub, ahead of a council meeting next week.

Since the COVID-19 pandemic, numerous businesses and hotels have shuttered their doors, many of which were located on Granville Street. Safety and homelessness have also become increasingly significant issues, with a 2021 report by Resonance Consultancy finding that Granville Street was "perceived as the most insecure area in Downtown Vancouver for both locals and tourists" and had become "mainly used as a transit corridor by Vancouverites commuting to Downtown Vancouver during the day, and as a nightlife destination in the evening."

In mid-April, Metrolinx announced that it had begun the final leg of tunnelling for the west extension of the Eglinton Crosstown LRT. This brings the long-awaited transit line closer to completion (although there’s still no opening date in sight), and a 16-storey rental slated for 1641 Victoria Park Avenue is one example of housing that will benefit from the forthcoming transit connectivity.

The 12,679 sq.-ft site, which is on the east side of Victoria Park Avenue near the Arncliffe Crescent intersection, is currently occupied by a two-storey building that had previously been residential, but has since been adapted for office uses. The property is within walking distance of a future O’Connor Station stop of the Eglinton Crosstown LRT, according to the planning report.

Canadian non-mortgage delinquencies reached "levels not seen since 2009" in the first quarter, while mortgage delinquencies in Ontario hit the highest point ever recorded by Equifax, according to the credit bureau's latest Market Pulse Consumer Credit Trends and Insights report.

In Ontario, the 90+ day mortgage delinquency rate rose to 0.24%, which marks a "substantial" 71.5% increase from a year ago, and British Columbia followed with a notable 33.3% increase in 90-day delinquencies — unsurprising given that these provinces are home to some of the most expensive housing markets in the country. Ontario also led the nation in non-mortgage delinquencies, up 24% year over year, followed by Alberta at 15.9% and Quebec at 13.9%.
