I would like to know where iI can purchase this from Canada (3in1 combo).
This is a European stroller system that you'll only get to Canada via eBay, I believe. Here's an eBay link to find the sellers that do sell this pram with a possibility of delivery to Canada.
Be advised this is a rather budget-friendly (cheaper) pram normally, but the shipping will make it more expensive for you. But if you really crave it... ;-)
