In a post on its Facebook page, DBKL said the cancellation was out of respect for the victims of the sinkhole incident and a number of incidents that happened around the city recently.
It also invited the public to appreciate the meaning of National Day by showcasing their patriotism.
A visitor from India, Vijayaletchumy, 48, fell into the sinkhole at Jalan Masjid India last Friday.
In a separate statement last night, DBKL said the fire and rescue team had entered the sewage channel upstream from the sewage tunnel at Wisma Yakin, while manual shoring and excavation works had also been carried out.
The statement added that the search using the ground penetrating radar carried out by the mineral and geosciences department will continue.
