Your dormants will do just fine anywhere in Canada. You'll not only get plenty of winter chill, but the short winter photoperiod will have most of them underground by Thanksgiving. I'm in California, and have had no problem growing dormants such as Angel's Smile, Baruch, Dance Ballerina Dance, Emily Jaye, Spread Gold, Yuma, Joel, Demetrius, One Dreamer, Spellbinder, and My Sunshine.
