Hazards found at federally approved grow-ops

For the second time in as many months, officers with the City of Calgary have found numerous safety codes violations at a federally licenced medical marijuana grow operation.

On February 15, safety codes officers with the city executed a search warrant to enter and inspect a Health Canada licenced grow-op where they found electrical and water bypasses (indicating theft of power), evidence of a previous fire, illegal electrical wiring, serious mould growth, spider mite infestation on plants, and toxins and chemicals, says Wayne Brown, coordinator of the city’s Coordinated Safety Response Team (CSRT).

“We found similar safety hazards that are quite typical of the illegal [operations],” Brown says, adding that Alberta Health Services conducted its own inspection and issued an executive officer’s order deeming the building unsafe. “They found enough mould in that building to post it as uninhabitable,” Brown says.

For their part, the CSRT issued an order under Section 546 of the Municipal Government Act requiring the property owner to begin the process of remediating or demolishing the building within 60 days, Brown reports. The property owner vacated the building, the site was secured with fences and placards, and it remains shut down.


The discovery occurs less than a month after a similar inspection at another Health Canada-licenced location on January 18. That inspection also found multiple safety infractions including those relating to a compromised air intake system, toxins, pesticides, herbicides and fertilizers, and potential contamination of drinking water.

In both cases, the hazards found were similar to those of illegal grow-ops. Information from the City of Calgary says that common components of an illegal grow-op — such as complex wiring systems and timers, tanks containing chemical fertilizer blends and furnace bypass systems — pose a number of dangers to the public and responders. Some hazards include mould, chemicals, the possibility of explosion as a result of solvents and oxygen used, and electrocution and booby trap hazards for emergency responders.

Brown reports that the Ottawa-based Canadian Association of Fire Chiefs has written to Health Canada expressing their concerns with the current system for individual grow-ops. “There is a stronger likelihood you would have a fire in a grow-op than regular home [considering] just what kind of power you are using,” Brown says.

Public consultations into amendments complete

Gary Holub, a Health Canada spokesman, says that the federal government has completed public consultations into regulatory revisions to the Marihuana Medical Access Regulations and will be publishing the results of the consultations later this year.

“The medical marijuana access program and its regulations apply to individuals not to spaces or institutions at this stage,” Holub says. “One of the key reform agendas is in fact moving away from licencing individuals to licencing commercial enterprises for the production of medicinal marijuana for precisely this reason,” he says, referring to the Calgary incidents.

From a security and control point of view, Brown says that he would also like to see medical marijuana growing operations housed in commercial or industrial locations rather than municipal ones.

“I’m quite encouraged from what I am hearing from Health Canada,” Brown says, adding that he hopes “some of the individuals that have these legal grow-ops will come forward and invite us in and we will inspect them to make sure they’re safe.”

    There is nothing health and safety wise that makes a cannabis plant more unsafe then any other plant. Instead of singling out cannabis, government should make law that sets out what is required for a safe grow op of any kind, such as tomato plants. Patients often grow their own cannabis because they can not afford to buy it.

    If government takes away a right to grow cannabis current patient grow ops will likely be used for other plants, how does changing what plant is allowed in the grow op make the operation safe?

    I understand that firefighters have legitimate concerns but why is there no middle ground?
    Why is the answer take away the right to grow from patients who can’t afford it otherwise?
    Why isn’t the answer grow operations (of any kind) have to meet a safety standard before being approved?

    They are using this smear campaign on a few isolated incidents as an excuse to get rid of the patient’s right to grow. People grow indoors all over this country far and wide and a great many of vegetables are grown this way. Home grown indoor organic is a big thing these days, So why is it that only cannabis grown indoors is apparently some issue to be worried about all ov a sudden?
    What is next,…perhaps the goon squad is going to come kicking in your door for growing cucumbers and tomatoes? They must be since indoor growing so bad for our community!
    Give me a break…

    I agree.
    Inviting the fire inspector in is a good idea, a non disclosure agreement should be signed. And the inspectors should arrive in plain clothes. NO FIRE TRUCK … NO POLICE CARS… there-by protecting the good guys who are following the rules from the dangers of exposure.
    And … if there are code violations ( with in reason, not deadly ), a grace period should be issued. 7 days, 1 day , etc…

    lets get real, and make a difference, we are all in this together !
