Can a Pfizer or Moderna mRNA vaccine interval be stretched from 3-4 weeks to 4 months and still be effective?

I'm concerned at the lack of testing or trials to back the decision in Canada to delay the second dose to 4 months. Is significant protection lost by receiving the second dose at 4 months rather than 3-4 weeks? Should protection still be the same after second dose, regardless of when the first dose was given?
