Yeah month-to-month is another name for the same thing. Generally, you fall back onto a periodic lease if your fixed-term lease expires and you aren’t given another fixed-term lease to sign. With our current laws where I am, a period lease is actually incredibly secure, thanks to the relatively recent “no grounds evictions” ban. The two types of leases have the same “grounds” apply to each, except that “end of fixed-term lease” is one which obviously doesn’t apply to a periodic lease. So the current situation is that you get that immediate day-one “notice to vacate” because landlords desperately want to avoid you ending up on a periodic lease where you’re better protected.

My changes were basically “hey, fixed-term leases shouldn’t be less secure than periodic leases are”.
