Biggest problems for Canada to ramp up and build anything on the scale required for war, first off we have to have a product to build. Takes years now to design, model and test before it can be built. If something is to be sole sourced and built in Canada, first off you have consider we are what I think of as once a generation kind of builder. The governments over the last 70 plus years seems to think everything has a shelf life of 40 years or more. Tanks, replaced once every 25 to 30 years now, Leo 1s were ordered in 1976 ( leased ) then purchased 1977/78, replacing a 1969/70 purchase of Centurion tanks (Leo were part of a trade deal with Germany ) Leos were replaced in 2007 with Leo 2s.
So a trooper in the armour regiment could be 18 in 1976 and still be serving in 2007 at 49 and retire out on the Leo 2 .
Canada has given away its arms business outside of small arms and some AFV made in London.
Navy ships the last ships built of any size was in the 50/60s those ship builders are all retired , the ship builders with the Halifax classes are near retirement if not retired.
You cannot ramp up a work force to deliver a airplane a week, or a ship a month or tank every other week, unless your work force has the skill sets to build them more than once every 30 years. We do not even have the skillsets in Canada to over haul or refit a tank here. Have to have over seas companies do it because no one here has the work force trained to do it.
Dash 8 series of aircraft built between 1984 and 2019, 35 years of building 1258 aircraft, averaging 35.9 aircraft a year or 1 aircraft every 10 days. That is a no thrills aircraft, no jet engine, no weapons systems, and basic layout.
F35 model takes 41 500 labour hours to produce 1 aircraft. in 2021 they were scheduled to produce 156 aircraft, less than 1/2 aircraft a day. CH 47 chinook production rate is 72 models a year. 0.19 helicopters a day.
If the mighty US Machine cannot build a chinook in a day, Canada has no hope in hell of doing it. Every factory Canadian government of any level gets involved in to build a piece of military equipment seems to disappear soon as the last truck rolls out of the factory door and the tail lights disappear in the distance it closes the factory.
Canada has nothing to ramp up.
Lancaster bomber once full production was ramped up they could turn out 25 a week. First flew Jan 1941, operational by October 1941
Cost between 45 and 50 000 pounds , in 2009 would equal around 1.3 to 1.5 million pounds
430 aircraft were built in Canada ( no bombing of the plants or Canada during the war) 6947 were built as England was at war and being bombed.
HMCS Haida ordered April 1940, Launched 25 August 1942, commissioned 30 August 1943 cannot find a cost. How would you expect to build it faster if during a war with ship builders on the war footing and had a lot of experience building ships over 3 years and there no were electronics or computers, or other high tech gear to build and install.
Canada spent some where around 21.8 billion dollars on the Second World War.
HMCS Ottawa (229) the helicopter carrying destroyer 1956 to 1992 no replacements
HMCS Halifax
planned in 1977
Laid down 19 March 1987
Launched 30 April 1988
Commissioned 29 June 1992
12 ships cost over 4.3 billion ( 358 million dollars for each of them )
Canada is now thinking it will cost 84 Billion dollars to get a new fleet up and running , over 5 billion has been spent and nothing to show yet.
Aircraft, that is another 14.2 billion dollar program and first one on the ground in 2026, and operational by 2033, 2034
Canada cannot even ramp up and buy a simple handgun for the CF without taking 20 years to decide on one
9500 handguns at 7.6 million dollars ( 800 dollars each)
Last fighter jet made in Canada the CF 100 Canuck service dates 1952 to 1981, 692 produced.
The Canadair Sabre Jet, a copy of the American Jet with Canadian Modifications 1950-1958 1815 units produced.
Last military aircraft built in Canada that I can find is the Bell 412 helicopter, but it was assembled not designed or manufactured.
Other problem is Canada cannot sell American or other designs without approval of the design country , ( could not sell the old Hueys had to go back to the US for resale, arms agreements) so even if we did build it another country would control our sales unless it was 100% Canadian made. From the ground up. Navy ship 100 % Canadian designs, weapons systems 100 % Canadian Design, radar 100% Canadian, and the list goes on.
Hard to compete with the mighty US companies if their government can control our end user sales.
Just my opinion
