Just did some quick figuring based on on-line numbers.
A budget of something between 200 and 500 million CAD would suffice to supply a body of 32,000 with:
Uniforms, PPE, a smart phone, a side arm and a carbine.
A C9 and an M320 GL for each fire team.
A C6, a DMR and a CG84 for every two fire teams
A new Silverado 1500 4x4 Crew Cab every 4 years for every fire team.
....
In a 5% of GDP Universe (100 Billion CAD a year, 400 Billion every 4 years or 1 parliament), those numbers amount to rounding errors.
Ensure the primary reserve has at least those capabilities then you can start building your real army on top.
