Step-by-step explanation:
There are a few factors that will affect the processing time of your application and how long it takes to immigrate or come to Canada:
Country of residence: Some IRCC processing times vary depending on a person’s country of residence. Before Dec 2015, processing times for different services would be displayed according to the visa office. This was because applications for both permanent and temporary residence, visas, and permits, were processed by the nearest visa office. Today applications are moved around the global network of visa offices to make processing as efficient as possible, so your application may not necessarily be processed at the visa office closest to you, but rather at the office best designed to process your application efficiently.
Type of application: Processing times for different types of visas and permits also differ. The type of application, as well as the number of candidates currently being processed in that category, can both affect the processing time. If a program receives more applications than expected, then it may take longer to process.
Completeness: If an application is incomplete, IRCC may either refuse the applicant altogether, or they may request more information which can cause significant delays to processing
