[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:
'Quadra' 1995; formerly Ottawa 'N01' = ('B08 × 'U11');

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

p. 27: 'Quadra' is a full sibling of 'Frontenac'. It is a hardy rose with a trailing growth habit which flowers freely during a long flowering season, but it is mor susceptible to blackspot than other roses of this series. The double red flowers are fragrant and do not fade with age.

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'. 
....Another Simonet hybrid was S67. It was the progenitor of Quadra, 'Frontenac' and 'Nicolas'. With the progress of the breeding program the pedigree became more complex."
