'Javagallowa' ... I'd like to suggest that you go to 'CHARLOTTE'S DAYLILY DIARY' on this ATP Daylilies Forum .... Listed on the main page are about 50+ Canadian daylily sources listed predominantly by their retail nursery names - as well as their province. ... Most are in Ontario & Quebec Provinces plus there are some located in The Prairies & The Maritimes .... ALL are highlighted by province in that column (Thus easy to find by simply scanning down the list) . Some are simple retail nursery operations ... Some are actual daylily breeders (aka Hybridizers) who sell out of their personal gardens and/or by Mail-Order ....
Additionally, once you have the breeders' names you are able to find many of them listed 'inside' (On the 2nd page) BY their family name (ie 'Hillside' is actually Canadian breeder Dave Mussar who has several Introductions - both diploid & tetraploid - registered with our AHS.)
Lastly, I have personal experiences with many through actual visits to their gardens. The Ontario Daylily Society (ODS) has organized tours sometimes & on-site picnics for example. Plus, the AHS Region #4 has also arranged similar on-site visits over the years. (BOTH have dedicated websites)
Oooops! ... 'Last Lastly' .... Please don't be concerned by many of the Quebec locations & Breeders having their info listed in French. Many have a simple 'switch' to click on to bring up their site into English , and there are translating tools available to bring into use also. Several of the Quebec breeders routinely participate in AHS Regional Meetings/Tours & also our own ODS Can-Am meetings.
Trust this information is of assistance.
I have also ordered from those that Touch of Sky mentioned, they have great plants and are 
excellent to deal with.
