dangerous driving with conditional discharge!
6 months probation!
Can I apply for citizenship & sponsor my wife?
You will need to consult a lawyer with immigration knowledge and bring specific information about your charge and sentence.
My understandong is you can't apply while on parole and days while on parole cannot be counted in your physical presence days. It's possible you can't apply for citizenship even for four years.
Also in any interaction with ircc where they ask, you must disclose all of this. Not doing so can have severe consequences.
I think there is no risk of deportation or removal orders (ie loss of pr status) if no other convictions. But again - check with lawyer.
I do not know if you sponsor your spouse in these circumstances (or when or if other steps required, like having the conviction expunged.)
It's more complex than it seems because it depends both what you were charged with, the way they charge you (summary or indictable offence), the maximum terms under that offence, and the actual sentence.
You should not take as fact any non lawyer's advice, nor take general comments on internet as advice (including my comments above).
