About 50 people gathered in Tompkins Park on Friday to push for more Canadian help in the search for more than 200 abducted Nigerian girls.
The girls were kidnapped three weeks ago by the extremist group Boko Haram, which threatens to sell them into slavery.
Canada is providing surveillance equipment and the personnel to operate it to help in the search.
But Maria Carveth, who organized the Calgary event, says Canadians want the government to do more.
"The goal today is to let our government know that Canadians want to be part of the rescue efforts in Nigeria," said Carveth.
She is hoping Friday's gathering will encourage other people to speak up as well.
"It's going to show other communities that they need to take a stand and do the same and as many communities that can do it, it's going to show the government, this is what we want."
Members of Calgary's Nigerian community were among the crowd.
