You are NOT alone; both the FCC and Industry Canada allow appliances (Industry Canada under some conditions) to be exempt from specific requirements regarding radio interference. ICES-003 exempts certain appliances from being tested to limits on ("technical requirements relative to the radiated and conducted radio noise emissions") radiated and conducted emmissions:
1.1 This Interference-Causing Equipment Standard sets out the technical requirements relative to the radiated and conducted radio noise emissions from digital apparatus.
1.2.2 Sections 3 to 7 do not apply to digital apparatus used:
(f) in machinery, apparatus or equipment:
(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
(iv) where the machinery, apparatus or equipment is a portable tool and has an input power that does not exceed 2 kW.
However... if your dryer runs off *220 Volts*, it would appear the exemption might not apply!
I believe Industry Canada, like the FCC, does not actually exempt appliances from the requirement they not create harmful interference, but merely exempts appliances from the need to meet established limits which other digital equipment must.
