Sure, but if I were to rewind back to when we were saving for a house - when I was 20 years old... I was still in university, I was (at the time) working part-time earning ~$18,000 a year whilst attending university. The only eligibility criteria for CERB with respect to income levels was income in excess of $5,000. If the pandemic hit me whilst working at that job - I would actually have been earning more by staying on CERB for the period it covered ($2,000 per month * 12 months = $24,000 per year).
Not only that - CERB payments were exempt from CPP and EI - so you actually got to retain even more of your money. All that said - the money absolutely had to go out, and that situation is the exception, not the norm for sure. I just meant if you were fortunate enough to be living at home and receiving CERB, the above scenario could certainly have ramped up your ability to save for your own home - if you had the means to do so.
