The benefit of that dollar versus the cost of collecting it?

Is this the reason why the CRA has been generally turning a blind eye to the evasion of tax by foreign property owners?  

The false declarations of resident status, the failure to remit profit from property sales? Failing to declare overseas income and assets, knowing that the overseas country where the assets reside, does not have, nor will have, any desire to aid foreign governments concerning disclosure.

Because I tell you, honest working Canadians, including our immigrants and refugees, are looking askance at the unfairness of declaring and paying our fair share of tax, whilst the CRA and the Feds give a huge pass to the real one percent. The one percent who have managed to game the system - and are laughing at us - because the CRA has been instructed to only chase the low hanging fruit.
