This graphic is interesting https://en.wikipedia.org/wiki/Measles_vaccine#/media/File:Me... With one dose the case number is reduced a lot, but there are still some smaller peaks aver few years. After the second dose was made mandatory, the number of cases goes to almost zero.
I'm not sure about Canada, but here in Argentina kids get two doses, and every 5-10 years there is a effort to give an additional dose to some groups with more risk (like small children).
