No unfortunately not. It was received about 15 yrs ago through ordering from a “Sheila” of Rocky Mountain House. It started as a sucker/ runner l am told either from her garden or Erskine’s (Prairie Peace) who the family looked after in his declining years. Also got from her gleam and beauty of leafland. She disappeared from selling at least 10-15? years ago.
Forgot l got my 3 prairie peace from her as small runners. Like to think got them as about as close as one can get hybridizer’s certified “source” or “impeccable provenance”. No proof except geographical coincidence 
Occurred to me there is a slim chance if you email Osbourne of Cornhill Nursery ( New Brunswick) with a list of Canadian Heritage roses your looking for he may be able tell you if he has them.
He use to put them on his site but l believe he is retreating for commercial reasons from his “Heritage” and they disappeared from his site. Conjecture on my part.
Got Isabelle Skinner from him and a few of Erskine’s, Skinner, and maybe my Simonet’s Red Dawn x Suzanne.
