Pick a new phone number. Google the number beforehand so you can avoid picking one which has a bad history (or any public commentary at all, really). And never make it visible anywhere online, not in user profiles, not in social media - the moment it becomes public domain it'll hang around the search engines forever and be free game for anyone to target indefinitely.
Avoid submitting your phone number to legit businesses (like Walmart, London Drugs, etc). They can probably be "trusted" to protect your privacy (by promising to not share or sell your information). But they can't necessarily be "trusted" to keep your information properly secured (you have no control over what they do with it or who they hire to access it, and there's always news stories about consumer privacy leaks when large corporate/government databases get hacked or compromised).
The more visible your number becomes, the more scammers it will attract. And they apparently branch out or share lists of "live" numbers with each other... so if you respond in any way to one scammer (replying "unsubscribe" or even just answering your phone) then you can find yourself targeted by many more scammers. I don't ever answer private, blocked, or unknown calls - or calls from numbers with commercial area codes (1-800, 1-900, etc) - if it's important then they'll leave me a message and a way to call them back.
Register your new number on the Canadian Do Not Call List. It's government regulated, trespassers can face hefty fines.
Also signup on the USA Do Not Call Registry. Because a lot of telemarketer/survey stuff is USA-based businesses or outsourced for USA-based businesses.
These DNCLs only prevent legit solicitors from calling your number - there's always some who don't comply, there's always some who consistently get away with plausible "errors" which skirt the law, and there's always scammers/criminals who ignore laws anyhow - but less incoming garbage is still less incoming garbage.

It turns out that there's an outsourced call center near where I live which happens to have special privileges in and around my entire city because it (along with much of the city) is located on First Nations (reservation) land. I politely requested they take my number off their list and don't call it again, so far they've politely complied. This First Nations exception seems like a useful loophole for this sort of business so there's probably more like it all across Canada.
The only other thing you can do is Block/Ignore incoming numbers. And report these scams (to your carrier, the DNCL, the legit businesses/banks they impersonate, consumer scam-tracking sites/groups, etc) as you see them. Never 100% effective because they have access to a lot more phone number dodges than you do, but at least you can kill the cancer before it spreads.
Lucky Mobile advertises that they support UNCB (a tech feature which helps kill phone scams/fraud). I assume it's built into the Bell network (Bell, Virgin, Lucky), I suspect it's also built into the Telus side of the network (Telus, Koodo, Public), I've seen it mentioned in the marketing literature of some USA carriers. You can ask PM directly if they offer UNCB or something equivalent.

And, as usual, if you think your security might be compromised then run malware-scans on your phones/computers/devices and login from a clean/secure machine to change all your account PINs/passwords on everything from your email to your voicemail to your accounts/subscriptions to your banking/financial stuff.
