Moving to Canada Help!

My fiancé and I want to move to Canada in a few years and want to get started on any steps necessary to make it a successful move now. He currently owns a green cleaning company in the US and would like to continue running this company from Canada when we move. He does not want to branch out in Canada just continue to run the business from there. Would this be possible without getting majorly taxed by the Canadian government? Would it be best to get dual citizenship or can we live in Canada, get healthcare and qualify for other such programs (ie schooling for our kids etc) while still being American citizens?

On some other posts I also saw that in order to buy a home in Canada you have to have Canadian credit and 35% down! That seems a bit steep is this true throughout or is a factor of an ever-changing market? Would it be best to just rent a condo or apartment? Not sure how the credit would factor into that either.

We would really like to call Vancouver our home for at least a few years and just want to make the most educated and well planned move possible. Any advice would be greatly appreciated.

Thanks!

No. he would be resident in canada, thus subject to taxation there as well as in US.

You can't get Cdn citizenship until you've immigrated to canada, and then lived in canada for a few years. But none of the benefits you mention are reserved for Cdn citizens, just legal residents.

But, anyone needs to immigrate to canada, not simply move there. Unless you are educated, have a job offer, or can start a viable business IN Canada you cannot simply move.

Your other questions are way premature.
