The answer might surprise some, but no, you do not gain Canadian Citizenship by marrying a Canadian citizen.
Marriage to a Canadian citizen does not give you automatic citizenship. A misconception some prospective migrants, looking for an easy immigration road, might have is that by marrying a Canadian you will be granted Canadian Citizenship when in fact the only way to become a citizen is by applying for citizenship.
There isn't a special process for spouses of Canadian citizens. You must meet several requirements to apply for citizenship.
Meeting the requirements
Canada requires prospective citizenship application to be physically present in Canada and to have been a permanent resident of the country for at least 1,460 days during the six years immediately before the date of your application.
Applicants must also be physically present for at least 183 days during each of four calendar years that are fully or partially within the six years immediately before the date of application.
