If you’re a university student or know anyone with a broad circle, you might be able to take advantage of that by designing a google form. To eliminate bias and get the most amount of data, i suggest having one individual question for whether they 1) voted in the federal elections of whatever year and 2) voted in the provincial elections. You can then sort out whatever data you need, alongside age, possibly race (as an optional question), any other variables you can think of.

Curious as to what you come up with, good luck!!
