I’m also living in Canada (citizen) and considering to move to US. It’s not that it would be a huge disappointment if this wouldn’t happen but it seems that in US the housing market is way more cheaper (with some exceptions), taxes may be lower (some states may have lower taxes than what we pay over here). Also, job market is much more bigger with lots of opportunities to improve the income. The number one reason that I would consider for entering the lottery would be the weather. We can’t get used to the Canadian winter which is very long and depressing specifically for those with small kids. The weather is US is warmer. There are lots of benefits in Canada (crime rate, nice people, “free” healthcare, beautiful summers). If we will get our visas we will try to see if we can get a comparable paying jobs in US. If so and there is a cheaper house to buy than the one we currently own - this is no brainer in terms of improving our quality of life.
We were very lucky where both of us were selectee after entering for the very first time which is un heard of. My husband is selected from EU with a reasonable case number 21xxx while my Asian case number seems to be borderline with less chances (29xxx).
