Can a 30 year old date a 17 year old in Canada?

There is nothing that prohibits someone in Canada from “dating” a minor, sixteen years of age and younger, so long as the date does not involve sexual activity. As of 2008 the age of consent for sexual activity is 16 years. All sexual activity without consent, regardless of age, is a criminal offence.

What is the oldest age a 17-year-old can date?

As a 17-year-old, you may only have sex with someone who consents and is up to the age of 23, until youre 18 years old.
