Quick answer
Asphalt is still 80% of Calgary's residential roofs and modern Class 4 lines handle our hail far better than the 3-tabs the city used to be covered in. We install IKO, Malarkey, Owens Corning, BP and GAF.

Why architectural and 3-tab are obsolete in Calgary
Standard 3-tab and entry-level architectural shingles are rated for ~25–30 mm hail — exactly what we get every June. They're a false economy. Class 4 is $1–$2 more per square foot and lasts 10+ years longer.
