Lucas Smith Signature Real Estate is spearheading a record-setting event this week, bringing together real estate, community, and philanthropy in support of Make-A-Wish Canada.

From Oct. 2 at 4 p.m. to Oct. 5 at 5 p.m., the World’s Longest Open House will take place at Metric Homes’ model home at 51 Axel Crescent in Stittsville, West Ottawa. 

The event will run continuously for more than 73 hours, offering visitors the chance to tour the new home while helping raise funds and awareness for the children’s charity.

“You can come at 1 a.m. and grab a bowl of popcorn and join the Realtor on their shift,” said Lucas Smith.

According to research conducted by Smith and the organizing team, the current record of 72 hours was set in Colorado in March.

“It’s less about the record and more about the ability to raise funds,” said Smith.

Smith said the fundraising goal is to surpass $10,000. Funds are being raised primarily through corporate sponsors.

“This is more than an open house — it’s about building community, making history, and giving back. It’s for the kids,” said Smith. “We’re inviting everyone to come out, experience this incredible event, and help us support a cause that transforms lives.”

Smith challenges other Realtors to go for the record. He hopes to be back next year with a 74-hour marathon open house. 

Realtors from several brokerages banded together to pull off the event. They include Julian Hyams, Joel Leclerc, Serge Guénette, Tyler Verheul, RJ McComber, Meghan Courtemanche, Shawn McFarlane and Martin Clement.
