[RFI] Maytag Noise Generators

[Cortland Richmond]

Kirb, 

I don't know the specifically Canadian regulations and had to look them up.
Industry Canada has some tips. See 
http://strategis.ic.gc.ca/epic/internet/insmt-gst.nsf/en/sf05473e.html

Unfortunately, it appears Industry Canada may exempt digital devices in 
appliances from  meeting radiated and conducted emission limits:

ICES-003
Spectrum Management and Telecommunications Policy
Interference-Causing Equipment Standard
Digital Apparatus

(excerpt)
1.2.2 Sections 3 to 7 do not apply to digital apparatus used:
(i) the primary function of which is to apply energy to a process or
material 
through the action of an electric motor or a resistive heating element;
(ii) that draws a steady-state current that does not exceed:
(A) in the case of an electric motor, 20 A RMS;
(B) in the case of an electric heating element, used either alone or in 
conjunction with an electric motor, 50 A RMS;
(iii) that operates from an alternating current voltage supply that does
not 
exceed 150 V RMS; or ...

Harmful interference is still forbidden, of course. Check out the video at
the first URL above. 
Maybe it will help. And good luck!
