To increase your approval odds, first, send in a full and correct request with every paper needed. Make sure your passport is good, your trip plans are clear, and your bank papers prove you have enough money. Show you have strong reasons to go back to Canada, like a job, school, or family, to show you plan to return. If seeing friends or family, add a good invitation letter with proof. Travel insurance, where you're staying, and a good past immigration record also help. Putting in your request early and checking it for mistakes will help even more.
