Canada does not have a visa lottery system. Instead, they have immigration programs such as Canada Express Entry and the Provincial Nomination Program.

Express Entry is an online immigration system the Canadian government uses to manage applications such as the Federal Skilled Worker, Skilled Trades and Canadian Experience Class Program.

It is a point-based system; the candidates are awarded with points according to age, education, work experience, language proficiency and adaptability. 

The CRS system is also used to rank candidates in Express Entry Pool. Candidates with higher CRS scores have a better chance of being invited to apply for permanent residency. 

Another program is PNP, which allows Canadian provincials and territories to nominate candidates for permanent residency based on their specific economic and labour market needs.

Some provinces have enhanced PNP streams aligned with Express entry, giving nominated candidates additional CRS points, which increases their chance of getting an ITA. 

Express Entry candidates can also earn additional points for factors such as experience, education, job in Canada, or having a sibling living in Canada as a citizen or permanent resident.

The Canadian government regularly conducts Express Entry draws, issuing ITAs to candidates with the highest CRS scores. Invited candidates can apply for permanent residency.

Some streams, like Human capital priorities, target candidates with specific skills or work experience to meet the demands of the labour market.

Ontario Immigrant Nominee Program(OINP) stream may set different criteria regarding job requirements.

After the process of nomination and application is begun, candidates who are nominated through the PNP stream need to express interest, get a provincial nomination, and apply for permanent residency.

The provincial Nomination program proved beneficial for those candidates who are enabled to meet the CRS scores requirements for Express Entry.

Most important thing is the programs and immigration policies can change over time, so please check official websites of the Canadian government for the most up-to-date information.
