1. Had I missed that flight what, if any thing, would Air Canada have been obliged to offer me in terms of compensation?

They do not owe you any compensation, at least contractually. CoC are cear: their only obligation is to get to destination, period. No guarantee of time, route, they could even bus you.
If delay was weather related, they don't owe you anything. If it's something under their control, such as mechanical, they should provide you with a hotel room and some money for meals.
