Hiya on android will allow you to block numbers that start with a prefix, so you could block all calls that start with 604-233 604-232 and 604-234
Edit: I read a review of Hiya and it sounds like they're still missing what we're all looking for: "Two things are missing. First, the ability to block all calls not in contacts. I have to download a separate app for that. Second, on inbound calls from the same area code (i.e., spoofed numbers) it does not pre-screen the call."
