In addition to starting your own family, the following factors could be seen as proof of your ties to the country of residence:
I know all of these options sound like an overkill for a mere tourist visa, and nothing about this is fair, but there’s not much you can do about it. Mexico is a well-known "trampoline" for people trying to immigrate to US/Canada, and your situation lands you into this pile of statistically problematic applicants which don’t get visas.
Your interpretation of the reasons ‘made up’ is off.
It is a common reason to deny visa, one that is hard to fight.
Lack of ties to where you live is an other way of wording it.
Our usual advice is to wait a few years, wait till you have started a family of your own and can leave spouse and children behind as ties. Or hope that by that time the immigration officers see your longer stay in the country you live as a more secure position.
Having your parents living in the same country as you do is rarely enough for those ties to the place you live.
You may not see illegal immigration into Canada as an improvement of your life but many people in Mexico do and Canadian immigration officers have to deny visa if they suspect that going to happen.
It is unfair but at this moment in time it will be very hard to travel to any of the harder to get visa for countries and getting refusal will make it worse.
