My best bet to you is to do the medicals again in canada as u are now doing the application in-land..
yes the medicals get sent to the ottawa but in ottawa it goes to different departments and normally agents are lazy digging deep tofind u..
In-alnd meds go to in-land department., work permit renewal goes to work permit renewal section.. out-land meds gors to outland department., stdent visa = goest to student department.
eg - I did my medicals in canada b4 marrage and i was asked what is it was for i said work permit so i signed the work permit form and it went to ottawa work permit section/department.
when i got married in about 3 mnths time and i was filling the forms i realised that i needed to attached an outland medical reciept and i didnt have that so i call ie posted a thread on the forum and i was advice so..
went back to the same med place and asked and the lady was like no it will delay yr stuff as they will have to chase it. CIC dont want to chase stuff my dear...
Do a new one, it cost but u better off. I did a new one on the same day paid everything and the next day sent my appication i called med place to check on my med and the lady advice is gone to ottaw. . got approved and in - Process in London with meds recvd..... simple..
