The elevation of land surface above sea level has the least effect on the time needed for a river to form a canyon.
The least effect on the time needed for a river to form a canyon is likely the speed at which the river flows. While a faster-flowing river can erode material more quickly, factors such as the type of rock being eroded, the amount of sediment carried by the river, and the frequency of extreme weather events would likely have a greater impact on canyon formation.

The most important factor in making the Grand Canyon is TIME. The Grand Canyon has been made over thousands of years due to soil erosion as a result of water passing through the valley over the least path of resistance. Without the millions of years to produce the Grand Canyon, The river that passes in the middle of the Grand Canyon would not erode quick enough to create the giant Canyon we see today.
