But is ethanol one of those dangerous organic solvent or is methanol? What are the non-dangerous organic solvents? Are the non-organic solvents safer? Like butane? A dangerous to the consumer of the product or in the production of the product. I looked for more concrete information but have not found it yet. Wait, forgot about this one. Funny how all the limits are the same.
Limits for residual solvents in cannabis products.

Found a 2016 doc that says the following,
Access to Cannabis for Medical Purposes Regulations
Solvents
68 (1) Cannabis oil must not contain residues of solvents other than Class 3 solvents listed in the
Guidance Document — Impurities: Guideline for Residual Solvents, ICH Topic Q3C(R5), published by the Department of Health, as amended from time to time.
Residue limit
(2) Those residues must not exceed the limits established under that document.

LIMITS OF RESIDUAL SOLVENTS
Class 3 residual solvents (Table 3) may be regarded as less toxic
and of lower risk to human health than Class 1 and Class 2 residual
solvents. Class 3 includes no solvent known as a human health
hazard at levels normally accepted in pharmaceuticals. However,
there are no long-term toxicity or carcinogenicity studies for many of
the residual solvents in Class 3. Available data indicate that they are
less toxic in acute or short-term studies and negative in genotoxicity
studies.
Unless otherwise stated in the individual monograph, Class
3 residual solvents are limited to not more than 50 mg per day
(corresponding to 5000 ppm or 0.5% under Option 1). If a Class
3 solvent limit in an individual monograph is greater than 50 mg per
day, that residual solvent should be identified and quantified. The
procedures described in the Identification, Control, and Quantifica-
tion of Residual Solvents section of this General Chapter, with
appropriate modifications to the standard solutions, are to be applied
wherever possible. Otherwise an appropriate validated procedure is
to be employed. Such procedure shall be submitted to the USP for
evaluation. USP Reference Standards, where available, should be
used in these procedures.

Another few.
2016, many changes since, interesting they mentioned butane back then.
Another notable change from the former MMAR is that registered persons, as well as designated persons, will have the ability to alter the dried marijuana they harvest into other products, such as oils. In doing so, individuals are prohibited from using organic solvents (e.g., butane), given the health and safety risks posed by use of these products.
The inclusion of provisions enabling the production of products reflects the June 2015 decision in R. v. Smith. It should also be noted that registered clients of licensed producers also have this same ability to alter dried or fresh marijuana or cannabis oil into other products.

Ontario, 2018.
At this time, cannabis edible products and concentrates will not be permitted to be sold in Canada. The Federal government has stated that the sale of these products will be available approximately one year after the Cannabis Act comes into force.2 On October 17, 2018, individuals wishing to make their own cannabis edibles and other products for personal use will be permitted to do so, provided the use of dangerous solvents is not involved.

BC- Mission 2018
3.8 Use of Organic Solvents for Making Cannabis Concentrates
It is well known that individuals who grow their own cannabis also manufacture their own oils and
other products, such as shatter, using highly flammable organic solvents such as butane. Using
organic solvents to alter the chemical or physical properties of cannabis is prohibited by the Act
unless authorized by the Act. There have been several examples where explosions and fires have
started as a result of careless use of these solvents. While the District’s Zoning Bylaw prohibits the
sale, storage, or distribution of butane in quantities greater than 453 grams (16 ounces) in all
zones, changes to the Zoning Bylaw will prohibit the making of cannabis concentrates using
organic solvents throughout Mission unless authorized by the federal government.
