Should younger adults with no family history still get screened for type 2 diabetes?

It's still reasonable, particularly if other risk factors are present (certain ethnic backgrounds, PCOS, high blood pressure, or being significantly overweight), since family history is only one of several risk factors Diabetes Canada identifies, its absence doesn't rule out risk entirely. Standard screening typically starts around age 40 for average-risk adults regardless of family history, though a provider can advise on earlier screening if other risk factors apply to your specific situation.
