H&C would require you to have exceptional circumstances that are different thanDo you know when it will open again or how one can keep up with updates to know when to apply if it opens up again? I take it this the only way to sponsor parents?
the reasons people want to have their parents to join them in Canada. As already indicated if they get denied, traveling to Canada will be much harder. Some parents do get accepted but many get denied. The ability to now stay for 7 years under a supervisa may make it even harder to qualify under H&C. Supervisa is generally the best way for parents be with their children longterm. In general patent sponsorship is not guaranteed. There will always be more people wanting to sponsor their parents than spots available. Very few countries even offer parents sponsorship with access to public healthcare so even the chance to sponsor a parent and having a parent be able to visit for many years is much better than in most countries.
