Hood's proposal was for 150 Crusader-Rams, 150 Valentines, an unknown number of Light Tanks (over 50).
My general instinct is to combine all those and just produce one decent model of tank (with variants as needed), which would come to 350-400, not including any further deriviates (ie, Kangaroo, ARVs, Sexton type artillery, etc). Those kind of numbers seems to justify the design effort, as well as Canadian self-sufficience takes supply and production burdens off the Crown. There's also the option of supplying Australia or other like-minded allies.
Long range plans have Canada conducting further design work on armoured vehicles, so developing some kind of a Ram is somewhat needed to justify future developments.
