As a part of citizenship of Canada people are required to: a vote b keep their sidewalks clear C pay their respects d start a business

The answer is **a) vote**.<br /><br />While keeping sidewalks clear (b) is a civic responsibility in many places in Canada, it's enforced by municipal bylaws, not a requirement of Canadian citizenship itself. Paying respects (c) is a personal choice, not a legal obligation. Starting a business (d) is an option available to citizens and non-citizens alike. However, voting (a) is a right and responsibility specifically granted to Canadian citizens.<br />
