You're comparing a region of Mexico with the entirety of Canada? Some comparison. Invalid. Secondly, Canada (and the USA) have a good reporting system of crimes and have a universal classification system of what constitutes the various crimes - Mexico has neither.
If you're trying to say the Yucatan (and just which geographical area are you speaking of, the region or the state?) is a relatively safe part of Mexico for tourists to wander about and visit, that's my impression (also).
