You cannot obtain a license to drive a school bus if convicted under section 4 or 5 of the Narcotic Control Act of Canada within the last how many years?

Answer: D — Five years

If convicted under Section 4 or 5 of the Narcotic Control Act of Canada, you will not be able to obtain a license to drive a school bus within the last five years. This is because a conviction for a narcotic-related offense would raise concerns about an individual's ability to safely transport children. Therefore, options A, B, and C are incorrect as they suggest a shorter time frame for obtaining a license, which would not be in line with safety regulations and policies. Option D is the only correct answer as it provides a longer time frame for the individual to demonstrate they have rehabilitated and are fit to drive a school bus.
