Canada, who is from Tulsa, represented the Northeastern Oklahoma Coalition of Black Trade Unions. A diverse crowd of about  300 people rallied on the north side of the State Capitol Saturday morning, Aug. 24, 2013, to commemorate the upcoming 50th anniversary of the  1963 Civil Rights March on Washington.   Most of the crowd marched more than a mile from Stiles Park,  walking up Lincoln Blvd., to the statehouse. Many  in the crowd carried signs or banners, and some wore shirts bearing images of slain civil rights leader Martin Luther King Jr., who delivered his impassioned  oratory to a crowd of nearly 250,000 on the Washington Mall on Aug. 28, 1963.  At the time,  it was the largest demonstration ever seen in the nation's capital. King's remarks to the crowd, now known as the "I Have A Dream" speech, brought a national focus to the civil rights struggle in America and is credited with being a large influence to secure enough votes in Congress for the passage of the Civil Rights Act the following year.
