CANDU reactors don't make Pu out of the natural U we use as we break down to daughter elements. That being said, two things:
- We have lots of U. Enrichment is new to us, but we would be technically capable of starting. U bombs are possible, but not preferred for various reasons.
- If India can get Pu from a CIRUS (which was basically a NRX), we could develop nuclear weapon fuel here.
...and if Carney wins, he'll be PM but not an MP. The last time the PM was not a MP, it was John Turner. That was after Justin's father Pierre resigned. History is repeating.
The LPC lost badly under Turner in the next election - Cross your fingers.
