I know you are allowed to travel with up to $10,000 CAD or equivalent in foreign currency. I will be travelling overseas with my wife soon. Am I allowed $10,000 CAD and my wife is also allowed $10,000? or only $10,000 CAD for the both of us?
The Canadian government websites are not very clear on this point. For example this national website is written entirely in terms of one traveller and makes no mention of a family unit: https://www.cbsa-asfc.gc.ca/travel-voyage/ttd-vdd-eng.html
But this one for Ontario (which I would expect follows the same rules as the rest of Canada) says it's $10,000 per family: https://settlement.org/ontario/immigration-citizenship/landing-and-leaving/landing-in-canada/how-do-i-bring-money-into-canada-proof-of-funds/
Probably the best is just to declare if your family is carrying more than $10,000. You shouldn't get in trouble for declaring when it was not legally required to do so. And you are allowed to carry more than $10,000 so long as you declare it.
