[From "Felicitas Svejda: Who changed the way Northern Countries see Roses", by Claire Laberge & Roch Rollin, pp. 7-12]
After Dr Svejda retired, the rose breeding program was moved to Ag-Can L'Assomption Station where Ian Ogilvie (plant breeder) and Neville P. Arnold (plant physiologist) continued to release roses in the Explorer Series and worked on developing culture media for the micropropagation of all new cultivars selected for release. They introduced twelve of Dr Svejda's seedlings obtained from the tetraploid roses program. After the rose breeding program was moved again, some were also introduced from Ag-Can St-Jean-sur-Richelieu Station:

p. 26: 'Frontenac', 'Captain Samuel Holland' and 'Quadra' have been tested in Ottawa for five years.

p. 27: 'Captain Samuel Holland' has the same pollen parent as 'Frontenac' and 'Quadra', namely 'Félix Leclerc' (U11) but a different seed parent. It is a hardy pillar or climbing rose which flowers repeatedly and freely. It is highly resistant to powdery mildew and blackspot. The flowers are semmi-double, light red and slightly fragrant. At L'Assomption the plants reached 1.8 metres. I used it as pollen parent but selected no seedling.

p. 31: D25 was the pollen parent of U11 now named 'Felix Leclerc'. U11 was the pollen parent of 'Captain Samuel Holland', 'Quadra' and 'Frontenac'. 

p. 45: Graph 8 Climbers released from L'Assomption, QC....

‘Captain Samuel Holland’ = Arbuste. On peut, au choix, le tailler pour un faire un grand arbuste, ou palisser ses longs rameaux pour le conduire sur colonne… magenta intense, en solitaire ou en bouquets de 5 à 10, évoquent un peu des camélias avec leurs 24 pétales s’ouvrant quasiment à plat… parfum léger… s’épanouissent jusqu’aux gelées. L’arbuste étend vigoureusement ses longs rameaux retombants, bien garnis d’un feuillage vert franc et luisant. Ogilvie, Canada, 1992.
