If right now, they don't travel very well, is it permanent or only temporary due to their young age? My parents travelled a lot when I was young. Usually, they would take me with them and this was great. Thanks to that, by the time I was 10, I had seen a lot of different places (Greece, Turkey, Spain, Italy, Germany, etc) This was truly a eye/mind opener for me. So it it's possible, why not take them with you? Canada, which is a good place to start since you're so close and it's great for family holidays (camping, nature trips, canoeing, etc)

Occasionally, my parents went on their own. If it was for a short time (week end), a nanny would look after us. If it was for a longer time, we'd go and stay at relatives' (uncles, grandparents, etc) It made everyone happy.

And if you want to really get in touch with another culture, you can of course travel abroad, but you can also live abroad for a little while, and put your kids at an English speaking school.
