Summary of "Munitions List" Category 2-19:
 

The above summary by the Coalition to Oppose the Arms Trade (COAT) was derived from a detailed description of this category of munitions published by the Department of Foreign Affairs and International Trade Canada (DFAIT) in a document called A Guide to Canada’s Export Controls (June 2006).
http://www.international.gc.ca/controls-controles/assets/pdfs/documents/exportcontrols2006-en.pdf

The above DFAIT document describes seven different groups of products on the "Export Control List" whose export is "controlled" by the Government of Canada.  One of these seven groups, known as "Group 2" or the "Munitions List," is comprised of 22 categories of military products.  These are the categories of products whose export is documented in a series of DFAIT documents published since 1990, called Export of Military Goods from Canada.

Here is a quotation about this particular category of munitions from the relevant section of A Guide to Canada’s Export Controls:

2-19

Directed energy weapon systems (DEW), related or countermeasure equipment and test models, as follows, and specially designed components therefor:

a. “Laser” systems specially designed for destruction or effecting mission-abort of a target;

b. Particle beam systems capable of destruction or effecting mission-abort of a target;

c. High power radio-frequency (RF) systems capable of destruction or effecting mission-abort of a target;

d. Equipment specially designed for the detection or identification of, or defence against, systems controlled by 2-19.a. to 2-19.c.;

e. Physical test models and related test results for the systems, equipment and components controlled by this Item.

f. Continuous wave or pulsed “laser” systems specially designed to cause permanent blindness to unenhanced vision, i.e., to the naked eye or to the eye with corrective eyesight devices.

Note 1:

Directed energy weapon systems controlled by 2-19. include systems whose capability is derived from the controlled application of:

a. “Lasers” of sufficient continuous wave or pulsed power to effect destruction similar to the manner of conventional ammunition;

b. Particle accelerators which project a charged or neutral particle beam with destructive power;

c. High pulsed power or high average power radio frequency beam transmitters which produce fields sufficiently intense to disable electronic circuitry at a distant target.

Note 2:

2-19. includes the following when specially designed for directed energy weapon systems:

a. Prime power generation, energy storage, switching, power conditioning or fuel-handling equipment;

b. Target acquisition or tracking systems;

c. Systems capable of assessing target damage, destruction or mission-abort;

d. Beam-handling, propagation or pointing equipment;

e. Equipment with rapid beam slew capability for rapid multiple target operations;

f. Adaptive optics and phase conjugators;

g. Current injectors for negative hydrogen ion beams;

h. “Space qualified” accelerator components;

i. Negative ion beam funnelling equipment;

j. Equipment for controlling and slewing a high energy ion beam;

k. “Space qualified” foils for neutralising negative hydrogen isotope beams.
