I believe it is.
There certainly is going to be a burden of proof on the police in collecting evidence, and on the crown, to prove the intent. Many of these chemicals and apparatuses have dual purposes. They have perfectly legitimate purposes, but under certain sets of circumstances where people are known to accumulate chemicals known to be used for methamphetamine production and specific types of apparatuses that police commonly encounter in clandestine labs, such as 22-litre round-bottomed flasks, heating mantles that go along with them, and condensing columns, there is going to be a culmination of evidence brought together, along with whether or not there's an admittance from an accused, or overheard conversations, that would go to prove intent.
As for the simple fact of having a can of solvent at home or some of these other chemicals that a lot of us have at home right now, it's going to be a matter of the circumstances surrounding why they're in possession of those products and in what kind of state.
