I live in Yellowknife Canada and I am not sure what plants I can start with. My winters are 8 months long and temperatures are as low as - 50'c and my summers are short with about a high of 30'c.
Had a look at Google Maps and seems you live in an interesting area - lots of lakes there? I did see trees on the map... so I looked up native trees for the North West Territories:
www.enr.gov.nt.ca/en/services/forest-resources/tree-species-nwt
You could Google each one on the list combined with the word 'Bonsai' to see if the specific species is suitable.
Suitable are:
- Jack Pine
- Tamarack
A suitable deciduous tree could be the Dwarf birch (though this is Betula Glandulosa, not Betula Nana, and I did not find examples of it as bonsai).
The Paper Birch could work.
The Tamarack is a deciduous conifer.
Growing a bonsai for its flowers in your area I think will be difficult, unless when you have a greenhouse.
