100% agreed.
The above is not typical of how these things work.
A fairly standard package the City arrives at would look something like
- 6 months notice minimum
- you're welcome to relocate on your own
- a moving allowance may be provided
- you have the right of return for comparable rent
- typically relocation assistance is available (the builder or an agency they hire will help you find somewhere comparable);
- for vulnerable tenants and or those for whom comparable rent can't be found, the difference in cost is often picked by the builder for the term of construction (if you choose not to move back, you would have to pay market rent where you moved to)
Not every package is equally generous; though the right of return and ample notice are a feature of virtually all of them, as per the law.
That's certainly not to suggest we could not or should not do better; but the typical scenario isn't one of 'abandoning' tenants to the wilds of the market.
