People gathered at the Garden of Remembrance to celebrate the 15-year-old whose life ended a week ago.
Relatives, including his mother, marched through the streets of Dublin to the Dáil.
Community and church leaders, as well as Toyosi's cousins and neighbours addressed the crowd, before and after the rally.
Toyosi's kind heartedness and love of football were among the memories shared.
The National Public Services Alliance protest over pay cuts has been postponed to allow people to participate in the march.
Two people have appeared in court in connection with Toyosi's death.
