The Rondo and 5 both sell about 20,000 a year. About 40% of those sales are in Canada, 60% in the US.
It's hard to justify selling 12,000 of a model in a country with a population of 300,000,000 million, especially one that is priced low and supposed to be mass market, that's a tiny amount of cars compared to 500,000 a year the top performing models sell in the US.
8,000 in a population of 34,000,000 is not as bad, and compared to 60,000 cars a year the top performing models sell in Canada, is not a bad number.
In Vancouver I can often see 10 Mazda 5s a day easy. On a 3 day weekend trip to Seattle, I'd be surprised if I saw even 1.
