A draft's unlikely. Also, Canada recently signed an extradition treaty with the US, which means that draft-dodgers can't run there. However, by 'recently' I mean 'a year or two ago;' as recently as 15 years ago there was a big legal battle over Charles Ng, and Canada only sent him back over because they didn't want to get a reputation for harboring serial killers. But draft dodgers would be in Ng's company now. Not that there's going to be a draft.
