first of all, i don’t identify as latino, sorry!!! but anyway when i talk about mexico being treated the same way as canada, i mean, for example when it comes to prices, canada and usa have both of their dollars on the back of stuff, like if you bought a book in canada in the back it would say “10 usd/10 cad”, but no mexican currency? isn’t mexico also the neighbor and both nations have good ties?? it should be treated with the same level of important stuff
One part of this is history.
Canada and the US were British colonies; Mexico was a Spanish colony.
When some of the British colonies declared independence, they still had to trade with the colonies that hadn’t. People had relatives on both sides, the postal systems were integrated, indigenous people were mistreated in the same manner, and the list goes on. Culturally, the two remained very similar while the political systems differed.
Stuff coming from England often ended up in Toronto or New York; both of these cities became hubs of publication.
This is the way the relationship stayed pretty much up until NAFTA in the 1990s; books had already had over a century of being published in Toronto and New York for distribution across English North America.
Mexico had a different history, and a different relationship with California, Arizona, New Mexico and Texas. Instead of Mexico being a route for culture and European goods to enter the US, it was a source of cheap labor once slavery was abolished.
Unlike Canada where the most influential Canadians lived right along the border, in Mexico the influential Mexicans lived further south, with itinerant workers living along the border.
NAFTA changed the balance of trade somewhat, but it didn’t change the already established cultural norms or the places people lived.
Also English language books are going to be predominantly sold in English speaking countries. And it makes sense cost wise to target both markets together rather than printing individual runs priced for individual countries where possible.
And Canada and the US both use dollars; there is potential ambiguity in price for manufacturers and retailers, so better to clearly specify both. There is not ambiguity with the peso - if a customer sees a book is $10 they will know there is a different price in pesos.
