I'm also in Manitoba (jsut south of Winnipeg, Z3), so I can tag on here:
Most everything I planted over the last two years survived the winter, but definitely some with winterkill, here's my list. All survived well unless noted:
PLUMS
Opal plum on mustang rootstock - took winterkill to snowline
Canada
Brookgold
Ivanovka
Ptitsin#5
Fofonoff
APRICOT
Debbie's gold apricot
CHERRY (Sour, Pin)
maskinoge
Crimson Passion
Cupid
Romeo
Juliet
APPLES - all grown as espaliers, 1st tier at 18", then 12" apart
Prairie Sensation
Red Wonder
Redfield
PEARS - these had snow heaped on them up to 3-4' high. A few went above the snow line and had winter kill as noted.
So Sweet
Ussurian
Schroeder
Favoritka
Beedle
Flemish Beauty - may have taken winterkill above snowline, BUT i think what actually killed it was high standing water. Both it and Pattern leafed out fully, then died down to much lower on the trunk. I think its because our yard has been oversaturated due to spring flooding and nonstop rain.
Patten - same damage as flemish beauty
PEACHES
Contender on Krymsk 86 - Severe winterkill above snowline, only 1 branch leafed out that was under the snow.
Bailey seedling
Harrow Diamond on Bailey - Flowered and pushing fruit!!!
Saturn Doughnut on Bailey - DEAD. failed to leaf out. Trunk passed the green-scratch test early in spring, but failed to develop any new buds and leaf out. Appears dead.
APPLES
Collet seedling
Transparent Yellow on B118
Kerr
Norkent
Parkland
Sept Ruby
Goodland
GRAPES
Osceola Muscat
Bluebell
Swenson Red
Brianna
I'm looking for more peach seeds to try growing - if you have any to share, please let me know!!!
