Note 3: The containers inside the package are not required to bear TDG dangerous goods marks or dangerous goods safety marks.

Dangerous goods that can be shipped under this exemption will have a limited quantity index greater than 0 in Column 6(a) of Schedule 1 of the TDG Regulations.

This updated course provides an overview of the Transportation of Dangerous Goods (TDG) Act and Regulations. It reflects the most recent regulatory amendments in (SOR/2023-155) and (SOR/2023-206) published in the Canada Gazette, and other significant content updates.

Clark said that the Ottawa police officers dealing with the protesters have been laughing and trying to antagonize them. He said he asked an Ottawa police officer why they are doing this and the officer replied, “We are tired of this.”

Dangerous goods marks or dangerous goods safety marks are the first line of communication about the hazard(s) of the dangerous good. This communication is accomplished by the:

This mark is required when shipments meet the limited quantity exemption and must be displayed on one side of a means of containment that is visible when stacked.

This sign must be displayed on each side and on each end of the large means of containment (i.e., a total of 4 signs) next to each primary class placard for the dangerous goods or, if there is a subsidiary class placard, next to the subsidiary class placard.

In another incident, Ottawa police tried grabbing a woman protester and take her away because she wouldn't give her name. This may be considered "carding" by police. When a man tried to pull her back and help her, Ottawa police forced him to the ground.

"We are now returning to demand that the RCMP arrest Prime Minister Trudeau for treason because of his unlawful violent vaccine mandates, and his unlawful use of force to break up the protest.”

Clark said that the man who police Tazered had honked his horn and then was walking across Wellington Street and headed to the Parliament building. That’s when police ran after him, tackled him, and threw him to the ground face first.

A spokesperson from Ottawa Police Service told SASKTODAY.ca that, “We are aware of a video circulating on social media involving an officer using a taser. We do not have further comments at this time.”

Clark said when Ottawa Police Service officers saw him video recording the incident with his cell phone they then pointed the Tazer at him and threatened to use it against him.

Note 2: Package compliance marks are specified in the standard that the package or container is compliant with. This requirement is outlined in Part 5 of the TDG Regulations.

Placards are not required for overpacks as the definition and description for an “overpack” does not include “large means of containment”.

"Also, CSIS announced that the convoy protest did not meet the standards of a national security breach required by the Emergencies Act," it added. "These counterfeit emergency regulations infringed upon our basic human rights and our fundamental freedoms. We were beaten for no reason, our trucks were damaged and confiscated without legal cause or authorization, and many of us were criminally prosecuted with unreasonable bail conditions; all because we were exercising our inalienable right to freedom of speech, peaceful assembly, and association. We had an important public message and we protested peacefully in a symbolic location."

NOTE: The TDG Regulations have specified circumstances when this placard is not allowed to be used. See Section 4.16(2) of Part 4 in the TDG Regulations.

NOTE: The table below is for guidance purposes only. Other requirements may be listed in other sections, regulations, Codes, or Acts that are not listed in this table. For more details, consult the legislation directly. Always consult the legislation that applies in your situation.

NOTE: Dangerous goods marks or dangerous goods safety marks are considered to be covered if the means of containment (e.g., barrel, package, intermediate bulk containers, jugs, etc.) with the dangerous goods mark or dangerous goods safety marks is inside a closed vehicle and the dangerous goods mark or dangerous goods safety marks is not visible from the outside of the vehicle.

When a consolidation bin is used, the class of each dangerous good contained in the bin must be marked on a tag or on a fixed display device attached to the bin. The device can be either a tag or a fixed display device (e.g., a whiteboard or a piece of paper) that will be updated every time a dangerous good is removed or added (Section 4.10.2 in the TDG Regulations).

SASKTODAY.ca has reached out to several of the protest organizers asking them if they think calling for the arrest of Prime Minister Justin Trudeau is too extreme. They have not responded to interview requests.

Yes. The labels must be displayed on any side of the outer surface of a means of containment other than the side on which it is intended to rest or be stacked during transport. For a cylinder containing dangerous goods, the label must be displayed on or near the shoulder of the cylinder as shown below [Subsection 4.10(3)(b)].

“His wife was screaming ‘don’t do that he has had a heart attack twice.’ I didn’t realize it was legal for police to Tazer a restrained compliant citizen who was struggling to breathe.”

RCMP HQ in Ottawa was asked if they have received the demand letter from the truckers yet and if they plan to “arrest” Trudeau. They have not responded to the questions.

Examples are available from the TDG Directorate’s FAQ in Part 4 under the question, “Can you explain the current placarding requirements?”

Independent Ottawa journalist and political commentator who goes by the name of Patriot Smoothie, posted on Facebook that the gentleman who was Tazered by Ottawa police was a senior citizen.

On social media, Patriot Smoothie posted photos of the elderly man's injuries and said that he was Tazered twice. His wife has said that he has had two heart attacks in the past.

This is used to display the UN number on a large means of containment (greater than 450 L) when the UN number is not included in the hazard class placard.

See the images below for examples of how to place the dangerous goods placards on large means of containments such as a highway tank (Figure 3), and compartmentalized means of containment (Figure 4).

When a shipment consists of batteries with different UN numbers, all applicable UN numbers must be indicated on one lithium battery mark or the UN numbers can be included on separate lithium battery marks.

Note that the difference between labels and placards is their size. A label is used for a small “means of containment” whose capacity is 450 L or less. A placard is used for a large “means of containment” whose capacity is more than 450 L.

Dangerous goodssymbols

Large means of containment: These words must be displayed on two opposite sides of the large means of containment in addition to any other safety marks that are required under the TDG Regulations.

Placards are not required or are optional for some dangerous goods when the gross quantity of the dangerous goods is 500 kg or less. See Table 1 below for placard requirements.

“Misleading" dangerous goods marks or dangerous goods safety marks are safety marks that might be deceptive, ambiguous, or provide false information about the presence or nature of any dangers. For example:

Depending on the classification of the dangerous good, one or more of the following safety marks may be required on a small means of containment:

“Late this afternoon, @ottawapolice were on scene in the area of Parliament Hill to ensure public safety was maintained during a demonstration. Some protestors were using large speakers and loud hailers in contravention of By-laws. After various interactions with police, three people were arrested for obstruction and later released on conditions. While it is the duty of police to support legal demonstrations, we will not tolerate behaviours that endanger public safety or violations of the Criminal Code, By-laws or Liquor Licence and Control Act.”

Groups of protesters from across Western and Eastern Canada are camped at two locations on private land outside of Ottawa. They stopped in Regina for one night on their way across Canada.

Class placards are not required or are optional  only for  dangerous goods (one or more)  with the following classifications that are present in the shipment:

The Class 9, lithium battery label, must be displayed on a small means of containment for the following dangerous goods:

TDG symbolsand meanings

Placards are not required for consolidation bins as the definition and description of a “consolidation bin” do not include “large means of containment.”

Note 1 – The TDG Regulations were amended on July 5/2023. The definition of “dangerous goods safety mark” was withdrawn from the TDG Regulations. However, the TDG regulations and many Transport Canada publications still refer to the former terminology of “dangerous goods safety marks.” Thus, we include both terms in our OSH Answer Fact Sheet. The current TDG Act legal terms and definitions are as follows:

The number of placards depends on the type of large means of containment, classification of the dangerous good, and the type of dangerous goods mark or dangerous goods safety mark that is required.

Which labels or placards that must be displayed depend on the classification of the dangerous good. The requirements for the display of the dangerous goods marks or dangerous goods safety marks also depend on:

Responsibilities for dangerous goods marks or dangerous goods safety marks depend on whether the handler of the dangerous goods is the:

Generally, if the shipment includes dangerous goods in Class 7, Radioactive Materials, then two labels are required on the small means of containment. The labels must be displayed on two opposite sides of the outer surface of a small means of containment. See Section 4.10(5) in the TDG Regulations for circumstances when labels are not required and the "Packaging and Transport of Nuclear Substances Regulations" for specific marking requirements.

This course is updated to meet Transport Canada's educational requirements under the TDG Act and Regulations, for all persons who handle, offer for transport, or transport dangerous goods by road. This course includes the SOR/2020-23 TDG regulatory amendment.

Generally, a large means of containment must have four placards (one on each side, one on the front and one in the back). However, the dangerous goods mark or dangerous goods safety mark requirements for large means of containment with a capacity of greater than 450 L but less than or equal to 3000 L (i.e., an intermediate bulk container) are:

NOTE: The size of the “Inhalation hazard” letters varies for different types of means of containment. See Section 4.23 of Part 4 in the TDG Regulations

NOTE: Generally speaking, a placard must be displayed for each of the dangerous goods transported in a large means of containment regardless of the quantity inside the container. Also, regardless of the quantity of dangerous goods on board, the primary class placard for each of the dangerous goods in a large means of containment must be displayed on each side and on each end of the “large means of containment” or “means of transport”. If two or more dangerous goods have different UN numbers but are identified by the same placard or placards, the placard is required to be displayed only once on each side and on each end of a large means of containment regardless of how many products in the large means of containment have that class (primary or subsidiary) [See Section 4.15 in the TDG Regulations].

If a small means of containment is placed inside another, and the outer container is not opened during loading, transport or unloading, the label is required only on the outer small means of containment.

They are demanding the resignation of Prime Minister Justin Trudeau. They say that the truckers were the victims during the convoy to Ottawa in February 2022.

This mark is required when shipments meet the excepted quantity exemption. This mark must be displayed on one side of a means of containment that is visible when stacked.

Depending on the classification for a dangerous good, one or more of the following dangerous goods marks or dangerous goods safety marks may be required on a large means of containment:

Yes. Permission for the use of safety marks that are not compliant with Part 4 of the TDG regulations is specified in some of the special cases in Part 1 of the TDG Regulations. When dangerous goods are packaged in small quantities so that the gross mass of the outer container is less than or equal to 30 kg, the TDG regulations allow the use of marks (i.e., labels) that are compliant with one of the following legislations:

Labels and placards are diamond-shaped (also referred to as “square on point”) and must be displayed as illustrated below.
