Beware nyssaman. Eucalypts can be invasive environmental weeds outside Australia. You don't really want to compromise your Canadian environment for the sake of indulging you garden 'wants'.
My advice is to do your research thoroughly and seek advice from the relevant environmental authorities before you go importing any seeds.
A number of Australian Eucalypts are causing major environemntal problems in the USA. Not sure about the precise species but I think the Florida Everglades is one area where they are causing problems.
