Can I apply for a G1 driver's license in ON while in Canada on visitor visa?

Could she already drive though? As in, did she have a license from her home country or an international license? Or was she trying to learn to drive?

She already had an equivalent full license in the USA. Perhaps, the requirements are different for the G1.

It isn't clear, but the requirements look the same whether its G, G1, or G2.
