Whomever told you that a T5 YMS visa requires a job doesn't know what the heck they're talking about and really needs to go and review their knowledge of that visa class. A
T2 (General) visa requires specific work sponsorship, a
T5 YMS visa does not - the whole point of the T5 is for young people to come to the UK as a holiday maker and work, as much or as little as they choose (if they choose to work at all) while they're here.
According to the
Official Home Office Guidance, all your wife needed was to be aged 18 to 30, have £1,890 in savings, and be able to show proof of Canadian citizenship. There is no mention of a required job offer.
Now, in regards to the Spouse Visa process, you've got part of the process correct.
Your wife completes the application and attends biometrics in Toronto (I'm assuming that that's where she is at the moment).
From Toronto,
your wife sends the application and all supporting documents to Sheffield. The people who do the biometrics should have the facilities available to help her submit everything via courier... when I did my biometrics in Vancouver, the people doing my paperwork had a stash of DHL packaging and waybills to send my application package to the consulate in New York (North American applications were still being handled there in mid-2012.... they were shifted to Sheffield in late 2012/early 2013) and they had extra waybills and packaging that I could purchase to include in my application package in order to have everything sent back to me via courier.... I took note of the waybill tracking number so I could track my package once my stuff was sent back to me.
There is no public access to the Sheffield processing centre so you aren't able to submit the application in-person... mail or courier access only.
There may or may not be communication from the Home Office in regards to the progress of the application... do not worry if your wife doesn't hear from them when they receive her documents or during the processing phase - it's nothing personal against you or your wife... they tell everyone that they'll be notified as their case progresses and, more often than not, they don't follow up on the application's progress.
I know for myself, I didn't receive a "docs received" email but I did receive a "your application is being organised to be sent to an Entry Clearance Officer for consideration" email and then heard nothing back until they notified me that my visa had been approved and my passport was en route back to me. That said, they've changed their tune in regards to the way they notify applicants about how their application is decided. They are deliberately vague and no longer say outright what the decision is during the email - just a "decision has been made" statement. Applicants must then wait for their stuff to come back in order to find out the decision... if no refusal letter is included, the applicant should check every page of their passport to see if there is a vignette attached to one of the blank pages... it won't necessarily be on the first blank page from the front so it's advisable to check the passport to see if they have put in the visa (mine was about 6 pages in... I've got mild OCD so this bothered me a little bit but I was just happy to receive my visa so I was o.k.)
One other word of note... don't bother spending your hard earned ££££ on the pay-per minute "Help" line... it's staffed by a 3rd party company that is wholly unrelated to the Home Office and the call centre can provide very little useful information in regards to specific applications.
