What you need to know about Tamarack Ottawa Race Weekend

Thousands of people will hit the streets of the national capital region this weekend for the Tamarack Ottawa Race Weekend.

It's the first in-person Ottawa Race Weekend in Ottawa since 2019, after the 2020 and 2021 events were shifted online due to the COVID-19 pandemic.

"We are absolutely ready to go," Race Weekend President Ian Fraser said.

"For a moment over the last couple of weeks, over the weekend, I really didn't think about Tamarack Ottawa Race Weekend. I was more concerned with the devastation that had taken place in our city."

Fraser says Race Weekend is a "positive" for the city.

"We are so pleased to be back in-person," Fraser said.
