Please, please be very careful about this. I highly recommend contacting a knowledgeable refugee lawyer who can advise you before you apply for citizenship or renew your PR cards. You need well-informed legal advice before doing anything that could put your refugee determination and PR status at risk for cessation & loss of status in Canada. For more info, please check here:

Are you in Ontario? If so, please contact the Refugee law office or one of the Neighbourhood legal clinics, or a refugee lawyer who can advise you about when to apply for citizenship and under what circumstance to reveal that you renewed your home country passport and traveled to your home country.

Otherwise, contact a settlement agency and get their referral to knowledgeable legal help.
I'm not trying to be alarmist, or to say that visiting a parent on their deathbed is wrong. I say this because the risks being judged as having committed reavailment (reavailing yourself of the protection of the government you sought refuge from) could be grounds for cessation of your refugee (and PR) status. The CBSA has set a quota of the number of cessation referrals to the IRB. They are actively looking for cases of reavailment. Because the legal change allowing revocation of PR status is relatively new, no one really knows how the IRB or courts will deal with cases such as these.
But the risks are so high that one really needs to consult a knowledgeable professional with whom you can discuss the specifics of your case.
