It is very hard to do a proper survey. These are polling houses. Their job is to make it cheap and repeatable. It is a business. This alone generates bias.
An easy example is if you look at their response rate: Estimated Response Rate 11 percent, consistent with industry norms
Now they attempt to randomize (and it is hard to truly randomize) but within a sample, only 11% actually follow through. Why do people follow through? This is typically because they are ignorant, idle, or have an agenda. For example, I will never pick up a number I do not know. I will trace them, but if they do not leave a message, too bad. I will also never respond to a poll. I will never voluntarily give information. All of this is bias, and is considered a base reason why the Trump vs Hillary poll was considered flawed.
For me there are some important points:
1. If you are going to invest yourself in a poll, at least understand how valid they really are.
2. Any time you see a poll branded by CTV, or any news source, be afraid. It is there to generate headlines and $.
3. Realize these polls are there to make money. They try to be as accurate as they can, but their methodology is built to be cheap and repeatable, not accurate (that costs more).
4. Go look at the historical accuracy of these polls. In many cases, controlled distribution generators do better.
5. The government is not there to always reflect the majority. Minority rights are important. I consider the handgun ban a joke. There are real issues they can fix, but they are not as simplistic. The reason why this is getting pushed is because the Liberals are building their election platform, and they know the PCs will support the rights of gun owners.
