I don't think the Canadian electoral process will change for people living outside the country. The same provisions will apply to identity verification. What will change is that these people won't have to come back to Canada. They won't be subject to the limit of not living outside the country for more than five years. Canadians who spend more than five years abroad will retain their right to vote abroad.
Two general elections were held while I was living outside the country. I exercised my right to vote from the United States and Mexico. There are always very strict rules to follow to ensure the integrity of the vote.
