Mirella Radman knew the last place she wanted to be during the G20 summit was in her Queens Quay apartment, a seven-minute walk from the Metro Toronto Convention Centre.

So she decided to ditch her digs and, with that, nab an $8,400 windfall.

Three weeks ago, Radman posted an online ad for her one-bedroom apartment. Within a day, she received 10 calls and a handful of emails, including an offer from a U.S. Department of State official.

“I was flabbergasted by the demand,” she said.

Radman isn’t the only one cashing in on the summit. While many residents bemoan the endless disruptions accompanying the two-day conference, others — from earplug vendors to bodyguard firms — are using it as an opportunity to make some extra money.

Fuelling the G20 rental market is the shortage of hotel rooms. The few high-end, downtown hotels that still have rooms are inflating their prices. During the summit weekend, the Park Hyatt is charging $650 a night for a deluxe double. The following weekend, the same room is available for $276.

Sam Wong, meanwhile, is trying to take advantage of noisy demonstrations by selling specialized earplugs through his company, Marco Polo. His target client? Protesters. Delegates. Residents living nearby.
