I can't thank everyone enough for their input and insight!

It sounds like my discovery didn't miss some glaringly obvious form, checkbox, 
agreement or community (NO-US-EH, for instance <snark> ) to keep traffic from 
crossing the border.

Data *storage*, on the other hand, is a very different thing, and even a drunk 
intern can find the rules around that kind of thing.

Thanks again,

Subject: Re: US/Canada International border concerns for routing

It seems to me the original question was asking about it more from a legal 
perspective, in other words does Canadian traffic have to stay in Canada. IANAL 
(or a Canadian), but the answer is "mostly, no, especially as related to 
publicly routed traffic" as should be evidenced based on what's already been 
discussed here. In other words, there is restricted traffic but unless you're 
making a play for MAN/WAN type service on owned infrastructure, those 
requirements are unlikely to arise. 

To support the macro point, there is some big-boy level peering in Toronto but 
not really much else outside that, but there are plenty of routes that don't 
cross the border if you don't have to jump networks to your destination, for 
example going to an AWS on ramp in Canada using a native partner network, 
especially in the Toronto-Ottawa-Montreal.
