Some illegals do pay taxes and make claims if they are able to register under a false identity (eg. a deceased).

You make some very good points but I could point you to numerous cases where illegals do commit crimes yet they still dont get deported as they then appeal and in some cases win or their deportation is stayed based on Human Rights which may or may not be true.
We all know that in the low paying skills types of jobs certain employers will employ them as it saves them money ie no payroll or records of employment.
I cant fault an illegal wanting to work but lay blame on the employer in giving them a job and not doing their due diligence.
On a day to day basis illegals really don't affect us. We go about our daily routine. So now you get laid off and you are now finding it hard to get work in a non professional field. You know that X employer employs illegals and you wish to work there but there are no jobs available do you shop the employer to the authorities or go its oki I will look for work elsewhere.

Without a doubt shop the employer (if you know it is true). In many cases the illegal is being exploited and in some cases dangerously exploited.

In the computer industry, as on farms, the "employer" can reasonably be assumed to have knowledge that the workers are undocumented. It doesn't matter because there are multiple layers of shell company between the "employer" and the "employee". The "employer" has no obligation nor responsibility toward the "employee". I don't see that there's any blame to be laid, it's just business.

That's a ludicrous cliche. It's not the Grapes of Wrath. If, for example, buildings are to be built in the GTA, then the government should turn a blind eye. Nothing will get done if you send the builders home!

I wonder how the US would deal with this individual Abu Qatada the hate cleric currently in the UK

In the GTA they do turn a blind eye where construction jobs are concerned

Yes, my brother's first job here was standing in for people who'd been thrown out. He'd get a fortnight or so before the original worker came back. His employer had a fair number of staff in the GTA and in Calgary and there'd very often be one gone. Years later one of the owners of the firm moved to Australia, I asked why and was amused when he said it was because he could be legal there. Now that I reflect on it, he told me this in a pub where the bartender and one of the, three, partners, had no status in Canada. It's rampant, rampant I tell ya!

A friend of mine (Cradle Canadian) has just moved to California. They're a hairdresser, working in other people's homes and do a bit of painting on the side. Very easy to work and make a living without having status.

I have another acquaintance who did the same in Florida for more than 10 years, including owning a property. The challenge is not in staying, but being able to leave and come back. The former was caught and deported and likely will never be able to return.

It's relatively easy to do.

In the US you don't need a social security number to pay taxes or file a tax return, the IRS has the individual tax payer ID number for those who are foreign tax payers, illegals, or otherwise don't qualify for a SSN #. Since the IRS doesn't track immigration status of those who file taxes it's hard to say how many are illegal immigrants.

But most experts agree that illegals are and do pay taxes each year.

Some also use stolen or fake SSN's. Most employers don't check if the number is valid, only check to see if you have a SS card and an ID, some states will issue illegals ID's now, and its not exactly hard to create a social security card, its a flimsy piece of paper.

The US has a quota on employment-based permanent residency every year of 140,000, Canada allows more employment-based permanent residents than that in total numbers every year (around 150,000), let alone per capita and has one-ninth of the population.

It's fantastically easier to get a work permit to work in Canada than in the US. The H-1B quota for the US is 85,000 per year, and that assumes you are skilled enough to even qualify for it. As compared with Canada, where there is no quota. H-2A (seasonal agricultural workers) has no quota, but H-2B which is somewhat similar to the Canadian Foreign Worker programme has a cap of 66,000.

The US grants about a million people permanent resident status per year, whereas in Canada it is somewhere around 225,000, in a country with a ninth of the population and overwhelmingly people in the US get it through family-based immigration.

Without question it is a vastly more restrictive system as far as employment-based immigration goes. Even the fees are far higher.

To do that you have to get a waiver on I-601, which until recently was pretty hard to get.

How do you know the SIN is valid? This is a problem I mentioned on here before, there is no way to know.

There is no photograph on the SIN card, they could be using a fake SIN or more likely another person's.

In Canada there is a federal privacy Act but provinces can have their own if they want, and Alberta does. So I asked them how I could verify the SIN was real. Call the CRA they said, which I did and that tells you nothing if it has been stolen or borrowed.

The privacy dept. in Alberta told me I cannot require other ID unless it is related to the job. I can ask, but they don't have to show me.

The method they use is SINs that begin with "9" but that doesn't help if the SIN is stolen.

In the US you have to fill in form I-9 when you start work which requires you to show ID plus many employers use the E-verify system, I think there should be some equivalent to the I-9 in Canada.

There are still ways of defeating the US system but I won't go into them here.

Believe me I've done my due diligence, well beyond what the law required and it tells you f all.

Tell that to the Chinese cockle pickers in Morecambe Bay...oh wait, you can't.

In certain cases, a hairdresser, maybe some of your IT chums, where the risk to the public is low, and where there is no effect on wages, exceptions could be made. But generally it's in the public interest to discourage illegal employment.
