Hello, @LisaMarie.
I hope you're having a great week.
At this time, the feature to link a Canada and US accounts together isn't available. However, you can have two separate accounts that are Canada and the US if you'd like. I'll personally submit feedback to our product developers so they can consider this feature in one of the upcoming updates for QuickBooks.
The community has your back, so if you have any more questions, feel free to ask. Enjoy the rest of your week!
