The answer is that it isnt crystal clear until someone takes it to court.
MMAR licenses are all long expired but still valid.
The MMPR allowed for transfer of remaining months on the MMAR license.
When you did this, you had to physically give your license away.
At that time MMAR was repealed and it looked like home gardens would be ending.
Then came the injunction and patients could decide to keep their gardens.
Instead of forcing patients to give up MMAR licenses LP's began suggesting patients sign up for MMPR with a new document so they dont physically lose the old one.
I would think that any information listed on an LP's website should be true since Health Canada polices these sites.
Remember there is also a 150g limit that is fairly small if you are growing, drying and storing/curing, and purchasing from an LP.
