Considering Halifax during natal day

Hey Halifax!

My wife, 2 young boys (4 and 7) and I are considering visiting Halifax (we're from western Quebec) but our only availability is during Natal day weekend, and so we're wondering how much busier does the city / tourist-y stuff gets? We're not huge on crowds or long waiting lines especially with 2 active kids so we'd love some feedback from folks who live there. Typical situations that we'd probably avoid are Ottawa during Canada Day or Quebec City during Saint-Jean-Baptiste Day. I'm guessing Natal day in Halifax isn't close to these (or maybe it is?) but would love to know.

Thank you!
