Jet lag and toddlers in Canada Winter

We arrived in Canada, a 36hr journey from Australia on 15 Jan and it’s taking us 5 days to acclimatise to the time here. I’ve tried the going out in the daylight truck with the 1 and 2yr old but we’re all still out of whack!

I’ve only got 9 days left here and we’ve not done a lot. Hoping to get some advice on hacking this Jet lag with young kids!

Thanks.
