After the meeting, Baird was scheduled to hold a news conference at noon ET to discuss the latest developments in Ukraine. CBCNews.ca is carrying the event live.
Before their meeting got underway, Harper said the situation in Ukraine "is getting worse" and that Canada will take further action.
Harper described the recent events in Ukraine "strictly the work of Russian provocateurs sent by the Putin regime."
"I know this is a great concern to our NATO allies in the region, but it should be a great concern to all of us," Harper said.
"When a major power acts in a way aggressive, militaristic, and imperialistic, this represents a significant threat to the peace and stability of the world, and it's time we all recognized the depth and the seriousness of that threat."
Harper said Baird will travel to Eastern Europe this week for "high-level consultations on what further steps we can all take."
Baird will also travel to Egypt and Oman from April 17 to 20.
