Cherry Tree with Gisela 5 Rootstock

[Tenly]

Does anyone know of a Canadian nursery that carries self-fertile sweet cherries grafted onto the Gisela 5 rootstock?

No?

Does anyone know of a Canadian nursery that can import from the US?

These trees are supposed to be true dwarfs and only grow to about 10 feet tall and be hardy in Zone 4 and 5. Raintree Nursery in the US carries several varieties of these but unfortunately, they don't ship to Canada.

Thanks in advance for any help with sourcing this from within Canada.
