Hi HastyP, you are right that 1 (Canadian) squadron flew only hurricanes during the Battle of Britain. There were Canadian pilots who flew spitfires with other squadrons. A few examples are listed below.
P/O John Bryson 92 squadron
P/O Alfred Keith 'Skeets' Ogilvie 609 squadron
F/L P.G. St.G.O'Brian 152 squadron
F/L John Alexander Kent 92 squadron
P/O A.R. McL Campbell 54 squadron
F/Lt G.P.Christie 66 squadron
If you would like any info regarding the codes of spitfires flown by these squadrons send me a PM and I'll see what I can dig out.
Hope this helps
Martin
