The interview gave Kasky the opportunity to assert that the march, which is expected to draw as many as 500,000 to the nation's capital and hundreds of other cities around the country and even some overseas, was still controlled by the students from Marjory Stoneman Douglas High School in Parkland, Florida.
"No more silence, end gun violence", members of the Communities for Zero Violence, which organized the Toronto rally, chanted as they marched north along University Avenue in the city's downtown area.
One by one, the students from the Omaha Students Union, stepped up on to a small stage, leaned close to the microphone and raised their voices for the crowd of 1,500 people gathered at the Lewis and Clark Landing for March for Our Lives on Saturday.
"To all the kids from Parkland getting ready to use your First Amendment to attack everyone else's Second Amendment at your march on Saturday, I wish a hero like Blaine had been at Marjory Douglas High School last month", Colion Noir said.
Their deaths have reignited public anger over mass shootings and sparked a groundswell of protest throughout the us organized by some of the students who were at the school that day.

"Here in the USA, it's all about the money, and guns are a big part of how we make money", said Campbell, a gun owner who supports stronger gun control. "I don't want to be terrified of that either". Participants are fighting not just for students but for all victims of gun violence.
An NRA spokeswoman said it had not taken a position on the protests.
"Keeping our children safe is a top priority of the president's", said Walters, noting that on Friday the Justice Department proposed rule changes that would effectively ban "bump stock" devices that let semi-automatic weapons fire like a machine gun.
During the march Saturday, the NRA was conspicuously silent on Twitter.
"I want a future where he's not terrified of going to school, and he is not afraid anytime he goes out into a public place that somebody has a large weapon and can shoot him", Jennings said. "We go through the same thing everyone else in this country does too and... we're more than just five minutes on the news".

"I hope that our government will see that thoughts and prayers won't do much anymore", the Hinsdale Central student said.
