Did Canada develop or use a stove that was compatible with leaded fuel?
It appears that the immediate Canadian Army Overseas response to the fuel change-over was to start using British produced stoves.* They did however continue to search for a Canadian solution:
Coleman (USA) produced new models for the military (leaded fuel) market including the Models 520 and 523 although I haven't found any evidence that these were produced in Canada.
User manuals for the 520 and 523 can be found at these links:

Canada trialed the "Cookers Portable No. 523 Coleman Vehicular Model" in the fall of 1943 as Army Technical Development Board Project Number DOS(GS)-1810.
A limited description can be found in the minutes of the Army Technical Development Board Meeting #6, 5 October 1943, Ottawa:
"This type of Cooker is not as satisfactory as British Cookers Portable Nos. 2 and 3 and has not been adopted."

25 Apr 1944 - Canada still investigating possibility of using Canadian made stoves:
"With reference to proposed T.L.G. (Technical Liaison Group) visit to Canada.* Items concerning which the C.I.S Colonel Hidden and the D/C.I.S Lieut. Colonel Cothay request information are listed as follows -
A.****** Stoves - Various burners of the Cookers Portable No. 2 and No. 3 type that are produced and in use in Canada, particularly any types that may be adaptable for burning leaded petrol.* Col Cavey has had one Cooker Portable No. 2 Mk. III and one No. 3 Mk. III forwarded to N.D.H.Q. to compare with Canadian burners....."
