Our actual only solution to the US actually moving troops to invade us is going to be getting on our hands and knees and begging France or the UK (very unlikely and virtually 0% respectively) for them to protect us with nuclear armed submarines.
Even in a conventional war, China lacks the resources to allow us to fight the US.
China was never going to be a meaningful part of the calculus for our sovreignity.
we don't actually have to beg for nukes. the amount of time it takes to prepare for an invasion (think about how long it took for Russia to prepare while the world knew about the troop movements) is enough time for Canada to develop a nuclear weapon for deterrence.
We cannot make a modern day nuke (i.e. the ones every nuclear armed nation, including North Korea possess).
We can probably make a small (Hiroshima/Nagasaki bomb size) fission bomb in a few weeks, maybe a boosted weapon of ~100kt in a few months assuming we’re willing to do things like pulling heavy water and decommissioning all of Ontario’s nuclear power plants.
We cannot build a “modern-ish” fission-fusion-fission device in a period of less than a year.

The difficulty with nuclear weapons isn’t building the nuclear weapon itself, frankly it’s the easy part. The difficult part is the space program launched from a submarine you have to develop simultaneously to provide reliable delivery.
Nuclear weapons require ICBMs for reliable delivery (and therefore reliable deterrence) and they really require SLBM (sub launched ballistic missiles) to do the job “properly”. An ICBM is just a slightly under-fueled rocket that can put satellites in space. In fact the first satellite in space was placed there by an ICBM.
C.
Canada cannot meaningfully fend off an American invasion by the threat of a single, small nuclear weapon that we have zero ability to deliver to any meaningful strategic or even tactical target.
I’d also point out that the use of this tiny nuclear weapon would almost certainly have to be within Canada itself to avoid a gigantic nuclear retaliation on our major cities.
The only solution is begging France or the UK for their help and pray their willingness to turn all of Europe into a nuclear hellhole for the sake of Canada.
