I do not live in Canada but from what I can tell, your boat is required to have a builder’s compliance sticker affirming the the boat was built to Canadian small vessel regulations, but only vessels under 6m (19’8″) are required to include:
• what motor sizes are safe (outboard powered vessels only);
• how many people can be on board; and
• how much weight the boat can hold.
I could be wrong. So here is where I think you’ll find what you are looking for:
The Transport Canada Safe Boating Guide https://tc.canada.ca/sites/default/files/2024-03/tp_511e.pdf
The actual rules are in the Small Vessel Regulations:
https://laws-lois.justice.gc.ca/eng/regulations/SOR-2010-91/
pursuant to the: CANADA SHIPPING ACT, 2001
The specific regulations are at:

and over on the page at:

Hope this helps.
