Canada's consent laws are also more nuanced than just a bottom age:

A 14 or 15 year old can consent to sexual activity as long as the partner is less than five years older and there is no relationship of trust, authority or dependency or any other exploitation of the young person

A 16 or 17 year old cannot consent to sexual activity if:

• their sexual partner is in position of trust or authority towards them, for example their teacher or coach

• the young person is dependent on their sexual partner, for example for care or support

• the relationship between the young person and their sexual partner is exploitative

That's not the issue, though. The age of consent is a scape goat to distract from the actual source of the sex tourism problem. Colombia's laws for example are on par with the Canadian example quoted above. Yes the age of consent is technically 14, but there's a ton of nuance, like access to sexual rights (which was a big issue, like contraceptives and medical care). As well as strict rules regarding no more than 5 years of age gap.

The real problem is that both Thailand and Colombia have armed criminal groups controlling large swaths of territory where they engage in drug and human trafficking. With both, forced and sex labor intentions. Effective modern day slavery, due to a complex web of factors that make establishing the rule of law very hard. They're far from the only ones, tons of countries all over the world suffer from this issue regardless of age of consent.
