Why in the USA if you commit perjury you go to prison from one to five years (may vary based on the state), whereas in Canada is up to 14 years?

I want to make clear right from the beginning, but it should be obvious, that I’m not in favour of perjury. What I am against is the great amount of time which a person who commits perjury must stay in jail for. I mean, 14 years for perjury are roughly 1/6 of a person’s life. Is it really considered in Canada one of the worst crimes that could happen out there? I hope I’m not sounding biased, but to make sure I’m not, here are the sources of my research:
