Did you know that you do not need an agency to apply for a visa to Canada?

Yes. I have been recommending the people wanting to come to Canada NOT to use agencies for years.

It seems citizens of certain countries in particular want consultants or agents to do the work for them, and/or get them a visa when they do not qualify for one - i.e. they want help committing visa fraud. And those consultants scam them, scam consulates, etc. Participating in these scams is grounds for visa denial, or revocation with deportation/mandatory departure, and permanent bar to entry.

E.g. 1,076 foreign students from one country who used a fraudulent "education consultant" to get student visas to the US had their student visas revoked with deportation & permanent bar to entry. They are lucky they didn't get sent to prison first, as committing such fraud can get them a lengthy stint in prison for such fraud.

Not only does nobody need a consultant or agent to apply for a visa, they can be permanently barred from a country for using one. That's Fraud! Canada has denied student visas to tens of thousands of Indians for using a "consultant." Not counting those from other countries, likewise denied visas & barred. And they are permanently barred from Canada.
