Honest opinion, please.

Do your homework, Intercam is not legally a "bank." Be informed.

I have no idea what this means. Perhaps it's all in the name: "Intercam Bank".
They have ATMs, their cards can be used at other ATMs....and others have insisted they have no problem transferring funds from Canadian banks to their Intercam Bank accounts. That's the problem I have, but then again, I haven't pursued it with much enthusiasm, because I believe there wouldn't be much - if any - savings on currency exchange rates between Intercam Bank and my usual Zihua Scotiabank.
