Yup. There’s plenty of places along "the corridor" – Kitchener/Waterloo, Toronto, Ottawa and Montréal – in eastern Canada that could cater to the OP's goals and hop between them if there's a particular event happening in one of those cities (though not as a cheap as hoping around Europe).
Ottawa is nice, but I wouldn't recommend most companies in Kanata unless you're content with working in a cubicle farm in a bleak, suburban, commercial park hellscape.
Kanata is definitely the heavy hitter in terms of tech jobs, but the downtown has gotten way hotter in the past 5 years. Shopify, Klipfolio, Pythian, SurveyMonkey, EDC, etc.
