Yes, ignition implies burning, which means that you have a very rapid consumption of O2 molecules and the resultant flame. When you think of chemical changes, think of changes that are generally not reversible. like burning wood....you could never go back to the block of wood after it's ashes....that's because the wood has undergone a chemical change in which the actual make-up of the original "wood molecules" has been altered.
On the other hand, physical changes are reversible. These include things like freezing water. The water underwent a physical "appearance" makeover, but the properties that make water what it is have not changed. thus we can reverse the process and go back to liquid water.

Difference between physical and chemical changes?
Physical changes involve a change in the appearance or state of matter without changing its chemical composition, such as melting ice or changing the shape of a clay sculpture. Chemical changes involve a transformation at the molecular level, resulting in new substances being formed, such as rusting of iron or burning wood.
Is igniting fireworks a chemical or physical change?
chemical
Is igniting a firecracker a chemical change?
